“O Adonai,” as sung by Scott Turkington:
O Adonai, and Leader of the house of Israel, who appearedst in the Bush of Moses in a flame of fire, and gavest him the law in Sinai: Come and deliver us with an outstretched arm.
Here is the first of the O Antiphons. A wonderful demonstration is provided by Scott Turkington, in which he includes the Magnificat.
O Wisdom, which camest out of the mouth of the most High, and reachest from one end to another, mightily and sweetly ordering all things: Come and teach us the way of prudence.
