O Clavis David…
O come, thou Key of David, come,
and open wide our heavenly home;
make safe the way that leads on high,
and close the path to misery.
Emmanuel shall come to thee, O Israel.
Original text: O Key of David, and Sceptre of the house of Israel, that openeth and no man shutteth, and shutteth and no man openeth, come to liberate the prisoner from the prison, and them that sit in darkness, and in the shadow of death. (from the Dominican Sisters of Mary, Mother of the Eucharist postings on the O Antiphons)
 Thus says the Lord GOD of hosts, “Come, go to this steward, to Shebna, who is over the household, and say to him…  I will thrust you from your office, and you will be cast down from your station.  In that day I will call my servant Eli’akim the son of Hilki’ah,  and I will clothe him with your robe, and will bind your girdle on him, and will commit your authority to his hand; and he shall be a father to the inhabitants of Jerusalem and to the house of Judah.  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.  And I will fasten him like a peg in a sure place, and he will become a throne of honor to his father’s house.  And they will hang on him the whole weight of his father’s house, the offspring and issue, every small vessel, from the cups to all the flagons.
 But there will be no gloom for her that was in anguish. In the former time he brought into contempt the land of Zeb’ulun and the land of Naph’tali, but in the latter time he will make glorious the way of the sea, the land beyond the Jordan, Galilee of the nations.
 The people who walked in darkness have seen a great light;
those who dwelt in a land of deep darkness, on them has light shined.
 Thou hast multiplied the nation, thou hast increased its joy;
they rejoice before thee as with joy at the harvest,
as men rejoice when they divide the spoil.
 For the yoke of his burden, and the staff for his shoulder,
the rod of his oppressor, thou hast broken as on the day of Mid’ian.
 For every boot of the tramping warrior in battle tumult
and every garment rolled in blood will be burned as fuel for the fire.
 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.”
 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.
The zeal of the LORD of hosts will do this.
 Now when Jesus came into the district of Caesare’a Philip’pi, he asked his disciples, “Who do men say that the Son of man is?”
 And they said, “Some say John the Baptist, others say Eli’jah, and others Jeremiah or one of the prophets.”
 He said to them, “But who do you say that I am?”
 Simon Peter replied, “You are the Christ, the Son of the living God.”
 And Jesus answered him, “Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven.  And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it.  I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
