Introduction
Lord, open our lips, and our mouth shall proclaim your praise.
Lord, open our lips, and our mouth shall proclaim your praise.
Lord, open our lips, and our mouth shall proclaim your praise.

Psalm 3    Domine, quid multiplicati
Lord, how many adversaries I have!
how many there are who rise up against me!
how many there are who say of me,
“There is no help for him in his God.”
But you, O Lord, are a shield about me;
you are my glory, the one who lifts up my head.

I call aloud upon the Lord,
and he answers me from his holy hill;
I lie down and go to sleep;
I wake again, because the Lord sustains me.
I do not fear the multitudes of people
who set themselves against me all around.

Rise up, O Lord; set me free, O my God;
surely, you will strike all my enemies across the face,
you will break the teeth of the wicked.
Deliverance belongs to the Lord.
Your blessing be upon your people!

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

All praise your laying of the world’s foundation,
your Light eternal governing creation,
your Love exalted, fire from heaven descending,
hearts to rekindle.

Now in communion with the hosts of heaven
we join their praises, one in mind and spirit,
longing to join you in your peace eternal,
blessed for ever. Amen.

First Nocturn

Antiphon 1 There is one God Almighty: Father, Son, and Holy Spirit.

Psalm 8    Domine, Dominus noster
O Lord our Governor,
how exalted is your Name in all the world!
Out of the mouths of infants and children
your majesty is praised above the heavens.
You have set up a stronghold against your adversaries,
to quell the enemy and the avenger.

When I consider your heavens, the work of your fingers,
the moon and the stars you have set in their courses,
What is man that you should be mindful of him?
the son of man that you should seek him out?

You have made him but little lower than the angels;
you adorn him with glory and honor;
You give him mastery over the works of your hands;
you put all things under his feet:

All sheep and oxen,
even the wild beasts of the field,
the birds of the air, the fish of the sea,
and whatsoever walks in the paths of the sea.
O Lord our Governor,
how exalted is your Name in all the world!

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon There is one God Almighty: Father, Son, and Holy Spirit.

Antiphon 2 We confess you to be one in substance, Trinity in persons.

Psalm 18 (19)    Caeli enarrant
The heavens declare the glory of God,
and the firmament shows his handiwork.
One day tells its tale to another,
and one night imparts knowledge to another.

Although they have no words or language,
and their voices are not heard,
their sound has gone out into all lands,
and their message to the ends of the world.

In the deep has he set a pavilion for the sun;
it comes forth like a bridegroom out of his chamber;
it rejoices like a champion to run its course.

It goes forth from the uttermost edge of the heavens
and runs about to the end of it again;
nothing is hidden from its burning heat.

The law of the Lord is perfect and revives the soul;
the testimony of the Lord is sure and gives wisdom to the innocent.

The statutes of the Lord are just and rejoice the heart;
the commandment of the Lord is clear and gives light to the eyes.

The fear of the Lord is clean and endures for ever;
the judgments of the Lord are true and righteous altogether.

More to be desired are they than gold, more than much fine gold,
sweeter far than honey, than honey in the comb.

By them also is your servant enlightened,
and in keeping them there is great reward.
Who can tell how often he offends?
cleanse me from my secret faults.

Above all, keep your servant from presumptuous sins;
let them not get dominion over me;
then shall I be whole and sound,
and innocent of a great offense.

Let the words of my mouth and the meditation of my heart be acceptable in your sight,
O Lord, my strength and my redeemer.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon We confess you to be one in substance, Trinity in persons.

Antiphon 3 We profess it is always the same for you to be, to live, and to understand.

Psalm 23 (24)    Domini est terra
The earth is the Lord’s and all that is in it,
the world and all who dwell therein.
For it is he who founded it upon the seas
and made it firm upon the rivers of the deep.

“Who can ascend the hill of the Lord?
and who can stand in his holy place?”
“Those who have clean hands and a pure heart,
who have not pledged themselves to falsehood,
nor sworn by what is a fraud.

“They shall receive a blessing from the Lord
and a just reward from the God of their salvation.”
Such is the generation of those who seek him,
of those who seek your face, O God of Jacob.

Lift up your heads, O gates;
lift them high, O everlasting doors;
and the King of glory shall come in.

“Who is this King of glory?”
“The Lord, strong and mighty,
the Lord, mighty in battle.”

Lift up your heads, O gates;
lift them high, O everlasting doors;
and the King of glory shall come in.

“Who is he, this King of glory?”
“The Lord of hosts,
he is the King of glory.”

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon We profess it is always the same for you to be, to live, and to understand.

Antiphon 4 We call upon you, we worship you, we praise you, O blessed Trinity.

Psalm 28 (29)    Afferte Domino
Ascribe to the Lord, you gods,
ascribe to the Lord glory and strength.
Ascribe to the Lord the glory due his Name;
worship the Lord in the beauty of holiness.

The voice of the Lord is upon the waters;
the God of glory thunders;
the Lord is upon the mighty waters.
The voice of the Lord is a powerful voice;
the voice of the Lord is a voice of splendor.

The voice of the Lord breaks the cedar trees;
the Lord breaks the cedars of Lebanon;
He makes Lebanon skip like a calf,
and Mount Hermon like a young wild ox.

The voice of the Lord splits the flames of fire;
the voice of the Lord shakes the wilderness;
the Lord shakes the wilderness of Kadesh.
The voice of the Lord makes the oak trees writhe
and strips the forests bare.
And in the temple of the Lord
all are crying, “Glory!”

The Lord sits enthroned above the flood;
the Lord sits enthroned as King for evermore.
The Lord shall give strength to his people,
the Lord shall give his people the blessing of peace.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon We call upon you, we worship you, we praise you, O blessed Trinity.

Antiphon 5 Our hope, our salvation, our honor, O blessed Trinity.

Psalm 32 (33)    Exultate, justi
Rejoice in the Lord, you righteous;
it is good for the just to sing praises.
Praise the Lord with the harp;
play to him upon the psaltery and lyre.
Sing for him a new song;
sound a fanfare with all your skill upon the trumpet.

For the word of the Lord is right,
and all his works are sure.
He loves righteousness and justice;
the loving-kindness of the Lord fills the whole earth.

By the word of the Lord were the heavens made,
by the breath of his mouth all the heavenly hosts.
He gathers up the waters of the ocean as in a water-skin
and stores up the depths of the sea.

Let all the earth fear the Lord;
let all who dwell in the world stand in awe of him.
For he spoke, and it came to pass;
he commanded, and it stood fast.

The Lord brings the will of the nations to naught;
he thwarts the designs of the peoples.
But the Lord’s will stands fast for ever,
and the designs of his heart from age to age.

Happy is the nation whose God is the Lord!
happy the people he has chosen to be his own!
The Lord looks down from heaven,
and beholds all the people in the world.

From where he sits enthroned he turns his gaze
on all who dwell on the earth.
He fashions all the hearts of them
and understands all their works.

There is no king that can be saved by a mighty army;
a strong man is not delivered by his great strength.
The horse is a vain hope for deliverance;
for all its strength it cannot save.

Behold, the eye of the Lord is upon those who fear him,
on those who wait upon his love,
to pluck their lives from death,
and to feed them in time of famine.

Our soul waits for the Lord;
he is our help and our shield.
Indeed, our heart rejoices in him,
for in his holy Name we put our trust.
Let your loving-kindness, O Lord, be upon us,
as we have put our trust in you.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon Our hope, our salvation, our honor, O blessed Trinity.

Antiphon 6 Free us, save us, enliven us, O blessed Trinity.

Psalm 45 (46)    Deus noster refugium
God is our refuge and strength,
a very present help in trouble.
Therefore we will not fear, though the earth be moved,
and though the mountains be toppled into the depths of the sea;
though its waters rage and foam,
and though the mountains tremble at its tumult.

The Lord of hosts is with us;
the God of Jacob is our stronghold.

There is a river whose streams make glad the city of God,
the holy habitation of the Most High.
God is in the midst of her;
she shall not be overthrown;
God shall help her at the break of day.
The nations make much ado, and the kingdoms are shaken;
God has spoken, and the earth shall melt away.

The Lord of hosts is with us;
the God of Jacob is our stronghold.

Come now and look upon the works of the Lord,
what awesome things he has done on earth.
It is he who makes war to cease in all the world;
he breaks the bow, and shatters the spear,
and burns the shields with fire.
“Be still, then, and know that I am God;
I will be exalted among the nations;
I will be exalted in the earth.”

The Lord of hosts is with us;
the God of Jacob is our stronghold.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon Free us, save us, enliven us, O blessed Trinity.

Verse

May the Father and the Son bless us in the unity of the Holy Spirit. Amen.

Readings

Second Nocturn

Antiphon 1 The Father is love, the Son grace, the Holy Spirit fellowship, O blessed Trinity.

Psalm 46 (47)    Omnes gentes, plaudite
Clap your hands, all you peoples;
shout to God with a cry of joy.
For the Lord Most High is to be feared;
he is the great King over all the earth.

He subdues the peoples under us,
and the nations under our feet.
He chooses our inheritance for us,
the pride of Jacob whom he loves.

God has gone up with a shout,
the Lord with the sound of the ram’s-horn.
Sing praises to God, sing praises;
sing praises to our King, sing praises.

For God is King of all the earth;
sing praises with all your skill.
God reigns over the nations;
God sits upon his holy throne.

The nobles of the peoples have gathered together
with the people of the God of Abraham.
The rulers of the earth belong to God,
and he is highly exalted.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon The Father is love, the Son grace, the Holy Spirit fellowship, O blessed Trinity.

Psalm 47 (48)    Magnus Dominus
Great is the Lord, and highly to be praised;
in the city of our God is his holy hill.
Beautiful and lofty, the joy of all the earth, is the hill of Zion,
the very center of the world and the city of the great King.
God is in her citadels;
he is known to be her sure refuge.

Behold, the kings of the earth assembled
and marched forward together.
They looked and were astounded;
they retreated and fled in terror.

Trembling seized them there;
they writhed like a woman in childbirth,
like ships of the sea when the east wind shatters them.

As we have heard, so have we seen,
in the city of the Lord of hosts, in the city of our God;
God has established her for ever.

We have waited in silence on your loving-kindness, O God,
in the midst of your temple.
Your praise, like your Name, O God, reaches to the world’s end;
your right hand is full of justice.

Let Mount Zion be glad
and the cities of Judah rejoice,
because of your judgments.

Make the circuit of Zion;
walk round about her;
count the number of her towers.

Consider well her bulwarks;
examine her strongholds;
that you may tell those who come after.
This God is our God for ever and ever;
he shall be our guide for evermore.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon The Father is truthful, the Son truth, the Holy Spirit truth, O blessed Trinity.

Antiphon 3 The Father and the Son and the Holy Spirit are one substance, O blessed Trinity.

Psalm 71 (72)    Deus, judicium
Give the King your justice, O God,
and your righteousness to the King’s Son;
That he may rule your people righteously
and the poor with justice;

That the mountains may bring prosperity to the people,
and the little hills bring righteousness.
He shall defend the needy among the people;
he shall rescue the poor and crush the oppressor.

He shall live as long as the sun and moon endure,
from one generation to another.
He shall come down like rain upon the mown field,
like showers that water the earth.
In his time shall the righteous flourish;
there shall be abundance of peace till the moon shall be no more.

He shall rule from sea to sea,
and from the River to the ends of the earth.
His foes shall bow down before him,
and his enemies lick the dust.

The kings of Tarshish and of the isles shall pay tribute,
and the kings of Arabia and Saba offer gifts.
All kings shall bow down before him,
and all the nations do him service.

For he shall deliver the poor who cries out in distress,
and the oppressed who has no helper.
He shall have pity on the lowly and poor;
he shall preserve the lives of the needy.
He shall redeem their lives from oppression and violence,
and dear shall their blood be in his sight.

Long may he live!
and may there be given to him gold from Arabia;
may prayer be made for him always,
and may they bless him all the day long.

May there be abundance of grain on the earth,
growing thick even on the hilltops;
may its fruit flourish like Lebanon,
and its grain like grass upon the earth.

May his Name remain for ever
and be established as long as the sun endures;
may all the nations bless themselves in him and call him blessed.

Blessed be the Lord God, the God of Israel,
who alone does wondrous deeds!
And blessed be his glorious Name for ever!
and may all the earth be filled with his glory.
Amen. Amen.

Sing to the Lord a new song;
sing to the Lord, all the whole earth.
Sing to the Lord and bless his Name;
proclaim the good news of his salvation from day to day.
Declare his glory among the nations
and his wonders among all peoples.

For great is the Lord and greatly to be praised;
he is more to be feared than all gods.
As for all the gods of the nations, they are but idols;
but it is the Lord who made the heavens.
Oh, the majesty and magnificence of his presence!
Oh, the power and the splendor of his sanctuary!

Ascribe to the Lord, you families of the peoples;
ascribe to the Lord honor and power;
Ascribe to the Lord the honor due his Name;
bring offerings and come into his courts.

Worship the Lord in the beauty of holiness;
let the whole earth tremble before him.
Tell it out among the nations: “The Lord is King!
he has made the world so firm that it cannot be moved;
he will judge the peoples with equity.”

Let the heavens rejoice, and let the earth be glad;
let the sea thunder and all that is in it;
let the field be joyful and all that is therein.

Then shall all the trees of the wood shout for joy
before the Lord when he comes,
when he comes to judge the earth.
He will judge the world with righteousness
and the peoples with his truth.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Antiphon Glory and honor to God in the unity of the Trinity, to the Father and to the Son, with the Holy Spirit, for everlasting ages.

Antiphon 5 Eternity dwells in the Father, equality in the Son; in the Holy Spirit, the meeting of eternity and equality.

Psalm 96 (97)    Dominus regnavit
The Lord is King;
let the earth rejoice;
let the multitude of the isles be glad.
Clouds and darkness are round about him,
righteousness and justice are the foundations of his throne.

A fire goes before him
and burns up his enemies on every side.
His lightnings light up the world;
the earth sees it and is afraid.

The mountains melt like wax at the presence of the Lord,
at the presence of the Lord of the whole earth.
The heavens declare his righteousness,
and all the peoples see his glory.

Confounded be all who worship carved images
and delight in false gods!
Bow down before him, all you gods.
Zion hears and is glad, and the cities of Judah rejoice,
because of your judgments, O Lord.

For you are the Lord,
most high over all the earth;
you are exalted far above all gods.

The Lord loves those who hate evil;
he preserves the lives of his saints
and delivers them from the hand of the wicked.

Light has sprung up for the righteous,
and joyful gladness for those who are truehearted.
Rejoice in the Lord, you righteous,
and give thanks to his holy Name.

as it was in the beginning, is now,

He remembers his mercy and faithfulness to the house of Israel,
and all the ends of the earth have seen the victory of our God.

Shout with joy to the Lord, all you lands;
lift up your voice, rejoice, and sing.
Sing to the Lord with the harp,
with the harp and the voice of song.
With trumpets and the sound of the horn,
shout with joy before the King, the Lord.

Let the sea make a noise and all that is in it,
the lands and those who dwell therein.
Let the rivers clap their hands,
and let the hills ring out with joy before the Lord,
when he comes to judge the earth.

In righteousness shall he judge the world
and the peoples with equity.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,

Readings

Third Nocturn

Antiphon May praise resound to God the Father, and to his equal Offspring, and to you the desire of all time, the Holy Spirit, from the mouth of us all through the ages.

Canticle: Isaiah 33:2-10    Domine, miserere
O Lord, be gracious to us; we wait for you.
Be our arm every morning,
our salvation in the time of trouble.

At the sound of tumult, peoples fled:
before your majesty, nations scattered.
Spoil was gathered as the caterpillar gathers;
as locusts leap, they leaped upon it.

The Lord is exalted, he dwells on high;
he filled Zion with justice and righteousness.
he will be the stability of your times,
abundance of salvation, wisdom, and knowledge;
the fear of the Lord is Zion’s treasure.

Listen! The valiant cry in the streets;
the envoys of peace weep bitterly.
The highways are deserted,
travelers have quit the road.

The treaty is broken,
its oaths are despised,
its obligation is disregarded.

The land mourns and languishes;
Lebanon is confounded and withers away;
Sharon is like a desert;
and Bashan and Carmel shake off their leaves.

“Now I will arise,” says the Lord,
“now I will lift myself up;
now I will be exalted.”

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Canticle: Isaiah 33:13-16    Audite, qui longe estis
Hear, you who are far away, what I have done;
and you who are near, acknowledge my might.
The sinners in Zion are afraid;
trembling has seized the godless;

“Who among us can live with the devouring fire?
Who among us can live with everlasting flames?”

Those who walk righteously and speak uprightly,
who despise the gain of oppression,
who wave away a bribe instead of accepting it,
who stop their ears from hearing of bloodshed,
and shut their eyes from looking on evil,

They will live on the heights,
their refuge will be the fortresses of rocks;
their food will be supplied, their water assured.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.

Canticle: Sirach 36:14-19 (36:11-17)    Miserere plebi tuae
Have mercy, O Lord, on the people called by your name,
on Israel, whom you have named your firstborn.
Have pity on the city of your sanctuary,
Jerusalem, the place of your dwelling.

Fill Zion with your majesty,
and your temple with your glory.
Bear witness to those whom you created in the beginning,
and fulfill the prophecies spoken in your name.

Reward those who wait for you
and let your prophets be found trustworthy.
Hear, O Lord, the prayer of your servants,
according to your goodwill toward your people,
and all who are on the earth will know
that you are the Lord, the God of the ages.

Glory to the Father, and to the Son,
and to the Holy Spirit:
as it was in the beginning, is now,
and will be for ever. Amen.
