O Adonai and ruler of the house of Israel,
Who appeared to Moses in the burning bush
and gave him the Law on Sinai:
come with an outstretched arm and redeem us.
This antiphon is based on the follwing scripture:
Exodus 3:2 There 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 3:5 God said, "Come no nearer! remove the sandals from your feet, for the place where you stand is holy ground."
Exodus 3:13-14 But, said Moses to God, when I go to the Israelites and say to them, The God of your fathers has sent me to you, if they ask me, What is his name? What am I to tell them? God replied, I am who am. Then he added,This is what you shall tell the Israelites: I AM sent me to you.
Exodus 6:6 Therefore, say to the Israelites: I am the Lord. I will free you from the forced 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.
O Come O Come Emmanuel
Veni, veni, Adonai,
qui populo in Sinai
legem dedisti vertice
in maiestate gloriae
O come, o come, Thou Lord of might,
who to thy tribes on Sinai's height
in ancient times did give the law,
in cloud, and majesty, and awe.
