Psalms 137:9 ASV

⁷  Remember, O Jehovah, against the children of Edom The day of Jerusalem; Who said, Rase it, rase it, Even to the foundation thereof.

⁸  O daughter of Babylon, that art to be destroyed, Happy shall he be, that rewardeth thee As thou hast served us.

⁹  Happy shall he be, that taketh and dasheth thy little ones Against the rock. Psalm 138 A 'Psalm' of David.
