Psalms 137:7-9

⁷Remember, O Lord, unto the children of Edom the day of Jerusalem; who said, Raze it, raze it, even to her very foundation.

⁸O daughter of Babylon, who art wasted: happy he, that repayeth thee thy recompense for what thou hast done to us.

⁹Happy he, that seizeth and dasheth thy babes against the rock.
