The 2 'O' Antiphon: O Adonai

O  Adonai, * et Dux domus Israel, qui Moysi in igne flammae rubi apparusiti et ei in Sina legem dedisti: veni ad redimendum nos in bracchio extento.

O Adonai, * and Leader of the house of Israel, Who didst appear to Moses in flame of the burning bush and didst give him the law in Sinai: come, and with an outstretched arm, redeem us.

(Recording of the Antiphon sung by the Dominican student brothers in Oxford)
