O Antiphon for December 18: "O Adonai"

For December 18, the antiphon is based on Exodus 3:2, Isaiah 33:22; 63:11-12, Micah 6:4 and Acts 7:30-31.

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

O Adonai and Ruler of the House of Israel! You appeared to Moses in the fire of the burning bush and gave the Law on Mount Sinai: Come, and redeem us with outstretched arm.

Exodus 3:2: "An angel of the Lord appeared to him in fire flaming out of a bush.  As he looked on, he was surprised to see that the bush, though on fire, was not consumed".

Exodus 6:6: "Therefore say to the Israelites: I am Yahweh.  I will free you from the enforced labor of the Egyptians and will deliver you from their slavery.  I will rescue you by my outstretched arm and with mighty acts of judgment".

"Adonai" is Hebrew for "my Lord", and was substituted by devout Jews for the name "Yahweh", out of reverence. With this second antiphon we progress from creation to the familiar story of God manifesting himself by name to Moses and giving his law to Israel as their way of life. We are also reminded of the Israelites' deliverance from bondage under pharaoh - a foreshadowing of our own redemption from sin. The image of God's arm outstretched in power to save his chosen people also brings to mind the later scene of Jesus with his arms outstretched for us on the cross.
