The 'O Antiphons': O Adonai

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

O Lord and Ruler the house of Israel, who appeared to Moses in the flame of the burning bush and gave him the law on Sinai: come, and redeem us with outstretched arms.

The Pontifical North American College's version can be found here.

They also sing one of my favourite renditions of the hymn O Come, O Come Emmanuel which is a paraphrase of the 'O Antiphons'

Today's verse is:

O come, O come, thou Lord of might,
Who to Thy tribes on Sinai's height
In ancient times didst give the law
In cloud and majesty, and awe.
