Psalms 137:3-9

³For there our captors called for a song: our tormentors, rejoicing, saying: “Sing us one of the songs of Zion.”

⁴How can we sing the Lord's song in the foreigner's land?

⁵If I forget you, Jerusalem, may my right hand wither.

⁶May my tongue stick to the roof of my mouth, if I am unmindful of you, or don't set Jerusalem above my chief joy.

⁷Remember the Edomites, Lord, the day of Jerusalem's fall, when they said, “Lay her bare, lay her bare, right down to her very foundation.”

⁸Babylon, despoiler, happy are those who pay you back for all you have done to us.

⁹Happy are they who seize and dash your children against the rocks.
