Psalm 137:8-9

Wycliffe Bible

⁸ Thou wretched daughter of Babylon; he is blessed, that yieldeth to thee thy yielding, which thou yieldest to us. (O wretched daughter of Babylon; happy is he, who doeth to thee, what thou hast done to us/happy be those, who repay thee, for all that thou hast done to us.)

⁹ He is blessed, that shall hold; and hurtle down his little children at the stone. (Happy is he/Happy be they, who shall take hold of thy little children; and hurtle them against a stone.)
