Psalms 137:6

⁴  How shall we sing the LORD's song in a strange land?

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 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; happy shall he be, that rewardeth thee as thou hast served us.
