O Clavis David (December 19)

O Clavis David ("O Key of David") gets sung tonight as the Antiphon upon Magnificat.

O Key of David, and Scepter of the house of Israel; that openeth and no man shutteth, and shutteth, and no man openeth: come, and bring forth from the prisionhouse the captive, who sitteth in darkness and in the shadow of death.

Below is a Latin version of the Magnificat itself.



That text comes from Luke 1:

"My soul magnifies the Lord, and my spirit rejoices in God my Savior, for he has looked on the humble estate of his servant. For behold, from now on all generations will call me blessed; for he who is mighty has done great things for me, and holy is his name. And his mercy is for those who fear him from generation to generation. He has shown strength with his arm; he has scattered the proud in the thoughts of their hearts; he has brought down the mighty from their thrones and exalted those of humble estate; he has filled the hungry with good things, and the rich he has sent away empty. He has helped his servant Israel, in remembrance of his mercy, as he spoke to our fathers, to Abraham and to his offspring forever."

If you'd like to pray the whole office of Vespers, you can do it at St. Bede's Breviary; choose "Amplified Prayer Book" under "Style" to get the "O's".

The text for this antiphon is found in two places in the Scriptures: Isaiah 22 and Revelation 3:

Isaiah 22:22: And the Key of the house of David will I lay upon his shoulder; so he shall open, and none shall shut; and he shall shut, and none shall open.

Revelation 3:7: And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth....

Clearly, the Revelation passage is a direct quoting of the Isaiah; I am not yet certain of the significance of the phrase in either case, however.
