Psalms 137

1 By the rivers of Babylon— there we sat down and there we wept when we remembered Zion.

2 On the willows there we hung up our harps.

3 For there our captors asked us for songs, and our tormentors asked for mirth, saying, "Sing us one of the songs of Zion!"

4 How could we sing the Lord's song in a foreign land?

5 If I forget you, O Jerusalem, let my right hand wither!

6 Let my tongue cling to the roof of my mouth, if I do not remember you, if I do not set Jerusalem above my highest joy.

7 Remember, O Lord, against the Edomites the day of Jerusalem's fall, how they said, "Tear it down! Tear it down! Down to its foundations!"

8 O daughter Babylon, you devastator! Happy shall they be who pay you back what you have done to us!

9 Happy shall they be who take your little ones and dash them against the rock!
