1 By the rivers of Babel we [a]sat, and there we wept, when we remembered Zion.
2 We hanged our harps upon the willows in the midst [b]thereof.
3 Then they that led us captive, [c]required of us songs and mirth, when we had hanged up our harps, saying, Sing us one of the songs of Zion.
4 How shall we sing, said we, a song of the Lord in a strange land?
5 [d]If I forget thee, O Jerusalem, let my right hand forget to play.
6 If I do not remember thee, let my tongue cleave to the roof of my mouth: yea, if I prefer not Jerusalem to my [e]chief joy.
7 Remember the children of [f]Edom, O Lord, in the [g]day of Jerusalem, which said, Raze it, raze it to the foundation thereof.
8 O daughter of Babel, worthy to be destroyed, blessed shall he be that rewardeth thee, as thou hast served us.
9 [h]Blessed shall he be that taketh and dasheth thy children against the stones.
