Psalm 81

God is in the congregation of Jews: from whom, as a rose, has come forth the Mother of God. Wipe away my stains, O Lady: thou who art ever resplendent in purity. Make the fountain of life flow into my mouth: whence the living waters take their rise and flow forth. All ye who thirst, come to her: she will willingly give you to drink from her fountain. He who drinketh from her, will spring forth unto life everlasting: and he will never thirst. Glory be to the Father etc.
