Literary Context
Psalm 137 is a communal lament voiced from exile, moving from grief and memory to imprecation. After recalling life “by the rivers of Babylon” and vowing not to forget Jerusalem, the closing lines (vv. 7–9) pivot to calls for recompense—first toward Edom, then directly toward Babylon. Verses 8–9 serve as the climax, compressing the psalm’s outrage into a short, shocking payback formula.
