O Adonai

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. 

O Adonai, and leader of the House of Israel,
    who appeared to Moses in the fire of the burning bush
    and gave him the law on Sinai:
        Come and redeem us with an outstretched arm.

This text references Isaiah 11:4-5 and Isaiah 33:22

I forgot to include my sources for yesterday’s text, so I will put

Wikipedia, and I originally got this idea from the introduction to
Advent for Choirs
