Encore Post: 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.
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.
Moses was minding his own father-in-law’s business — his sheep — when he saw a bush on fire that did not burn up. When he went up to see what was happening, the Angel of the Lord (the pre-incarnate Son of God himself) spoke with him from the bush. He commissioned Moses to free the people of Israel from slavery in Egypt. Doing everything he could to avoid the subject, Moses asked for the Name of God. “I am who I am” the Messiah replied. (Exodus 3) That name we pronounce Yahweh. It is spelled with four consonants in Hebrew — יהוה (YHWH) After the Babylonian exile, the Jewish people decided not to pronounce that name so it could not be taken in vain. Instead, they said, “Adonai” which means “my Lord.” Wherever the Angel of the Lord appears in the Old Testament, this name is given to him. He revealed God’s Law to Moses on this same spot after the Exodus.
Because the Messiah is God, there is nothing that he cannot do. He loved his people Israel, so he sent Moses to free them. He displayed his power to free them with plagues and miracles, including the parting of the Red Sea. Later the Scriptures would describe it as his outstretched arm.
The prayer calls on the Messiah to come and redeem us — which he did. This time the miracle was not raw power, but the power of God himself paying the price of our salvation — not with silver or gold, but with his own blood. He himself became the sacrifice of our sin, paying its price in full.
One day he will come again in glory, to redeem the world once and for all, defeating death, sin and devil. On that day, his outstretched arm will restore all things and bring all to his throne. There all will confess Jesus Christ as Lord to the glory of God the Father.
O come, O come, Thou Lord of might,
— Lutheran Service Book 357, Stanza Three
Who to Thy tribes on Sinai’s height
In ancient times didst give the Law
In cloud and majesty and awe.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel!
