Psalm 137:5-9 (King James Version)
5 If I forget thee, O Jerusalem, let my right hand forget her cunning. 6 If I do not remember thee, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief [1] joy.
7 Remember, O Lord, the children of Edom in the day of Jerusalem; who said, Rase it, rase it, even to the foundation thereof. 8 O daughter of Babylon, who art to be destroyed; [2] 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 stones. [3]
