Psalms 137:7 ASV

⁵  If I forget thee, O Jerusalem, Let my right hand forget 'her skill'.

⁶  Let my tongue cleave to the roof of my mouth, If I remember thee not; If I prefer not Jerusalem Above my chief joy.

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.
