1  By the rivers of Babylon we were seated, weeping at the memory of Zion, 2  Hanging our instruments of music on the trees by the waterside. 3  For there those who had taken us prisoners made request for a song; and those who had taken away all we had gave us orders to be glad, saying, Give us one of the songs of Zion. 4  How may we give the Lord's song in a strange land? 5  If I keep not your memory, O Jerusalem, let not my right hand keep the memory of its art. 6  If I let you go out of my thoughts, and if I do not put Jerusalem before my greatest joy, let my tongue be fixed to the roof of my mouth. 7  O Lord, keep in mind against the children of Edom the day of Jerusalem; how they said, Let it be uncovered, uncovered even to its base. 8  O daughter of Babylon, whose fate is destruction; happy is the man who does to you what you have done to us. 9  Happy is the man who takes your little ones, crushing them against the rocks.
