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

2 There on the poplars we hung our harps,

3 for there our captors asked us for songs, our tormentors demanded songs of joy; they said, “Sing us one of the songs of Zion!”

4 How can we sing the songs of the Lord while in a foreign land?

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

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

7 Remember, Lord, what the Edomites did on the day Jerusalem fell. “Tear it down,” they cried, “tear it down to its foundations!”

8 Daughter Babylon, doomed to destruction, happy is the one who repays you according to what you have done to us.

9 Happy is the one who seizes your infants and dashes them against the rocks.

Not quoting this to express my support, just reminded me of of the genocidal Psalm 137
