Psalm 137:4-7 King James Version (KJV)
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.
