Antiphon #2 O Adonai – O LORD OF ISRAEL, – Adonai is Hebrew for Lord. Lord is the substitute term for Yahweh, the sacred, saving, Gospel name of God under the old covenant. “Say this to the people of Israel, ‘Yahweh the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’”
