The second of the great ‘O Antiphons’ O Adonai
O Adonai and Ruler of the House of Israel, you appeared to Moses in the fire of the burning bush and on Mount Sinai gave him your law. Come, and with outstretched arm redeem us. 1
Our God indeed reaches from the beginning of time, He was there in the burning bush appearing to Moses, gave the Ten Commandments forming the basis of the Law, and will come and redeem us all in due course. He was at the beginning, and is to be at the end, and in the middle He comes to redeem us all if we will let him.
