O Adonai 18 December
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.
Adonai Lord Isaiah 11:4-5, Isaiah 33:22
As we await the coming of our Lord, we pray “Even so come, Lord Jesus”.
