One of the most unsettling passages in all of the Bible is found in Psalm 137. Here, the psalm writer laments the exile of the Jewish people in Babylon. The psalm ends with these chilling verses:
Daughter Babylon, doomed to destruction,
happy is the one who repays you
according to what you have done to us.
Happy is the one who seizes your infants
and dashes them against the rocks (vv. 8-9).
How are we to understand this passage from Psalm 137?
