veni ad salvandum nos, Domine, Deus noster.

the hope of the nations and their Saviour:
Come and save us, O Lord our God.

O Rex Gentium, et desideratus earum,
lapisque angularis, qui facis utraque unum:
veni, et salva hominem,
quem de limo formasti.

O King of the nations, and their desire,
the cornerstone making both one:
Come and save the human race,
which you fashioned from clay.

For to us a child is born, to us a son is given; and the government will be upon his shoulder, and his name will be called "Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace." Isaiah 9:6

O Oriens,
splendor lucis aeternae, et sol justitiae:
veni, et illumina sedentes in tenebris, et umbra mortis.

splendour of light eternal and sun of righteousness:
Come and enlighten those who dwell in darkness and the shadow of death.

O Clavis David, et sceptrum domus Israel;
qui aperis, et nemo claudit;
claudis, et nemo aperit:
veni, et educ vinctum de domo carceris,
sedentem in tenebris, et umbra mortis.

O Key of David and sceptre of the House of Israel;
you open and no one can shut;
you shut and no one can open:
Come and lead the prisoners from the prison house,
those who dwell in darkness and the shadow of death.

And I will place on his shoulder the key of the house of David; he shall open, and none shall shut; and he shall shut, and none shall open. Isaiah 22:22

Of the increase of his government and of peace there will be no end, upon the throne of David, and over his kingdom, to establish it, and to uphold it with justice and with righteousness from this time forth and for evermore. Isaiah 9:7

O Radix Jesse, qui stas in signum populorum,
super quem continebunt reges os suum,
quem Gentes deprecabuntur:
veni ad liberandum nos, jam noli tardare.

O Root of Jesse, standing as a sign among the peoples;
before you kings will shut their mouths,
to you the nations will make their prayer:
Come and deliver us, and delay no longer.

There shall come forth a shoot from the stump of Jesse, and a branch shall grow out of his roots. Isaiah 11:1

In that day the root of Jesse shall stand as an ensign to the peoples; him shall the nations seek, and his dwellings shall be glorious. Isaiah 11:10

O Adonai, et Dux domus Israel,
qui Moysi in igne flammae rubi apparuisti,
et ei in Sina legem dedisti:
veni ad redimendum nos in brachio extento.

O Adonai, and leader of the House of Israel,
who appeared to Moses in the fire of the burning bush
and gave him the law on Sinai:
Come and redeem us with an outstretched arm.

But with righteousness he shall judge the poor, and decide with equity for the meek of the earth; and he shall smite the earth with the rod of his mouth, and with the breath of his lips he shall slay the wicked. Righteousness shall be the girdle of his waist, and faithfulness the girdle of his loins. Isaiah 11:4-5

For the LORD is our judge, the LORD is our ruler, the LORD is our king; he will save us. Isaiah 33:22

During the evening prayer of the Liturgy of Hours, which is also known as Vespers, the Church prays the beautiful prayer of Mary known as the Magnificat. Preceding the Magnificat, there is an antiphon which is simply a short verse which connects the prayer to the particular feast day or liturgical season. On the last seven days of Advent, from December 17th through December 23rd, the antiphon for Vespers is one of the so-called "O Antiphons". It is related to a particular title of Christ's, and the antiphon ends with a plea for the Messiah to come.

O Sapientia, quae ex ore Altissimi prodiisti,
attingens a fine usque ad finem,
fortiter suaviterque disponens omnia:
veni ad docendum nos viam prudentiae.

O Wisdom, coming forth from the mouth of the Most High,
reaching from one end to the other,
mightily and sweetly ordering all things:
Come and teach us the way of prudence.

And the Spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and the fear of the LORD. And his delight shall be in the fear of the LORD. Isaiah 11:2

This also comes from the LORD of hosts; he is wonderful in counsel, and excellent in wisdom. Isaiah 28:29
