Psalms 136:6-9

⁶Let my tongue cleave to my jaws, if I do not remember thee: If I make not Jerusalem the beginning of my joy.

⁷Remember, O Lord, the children of Edom, in the day of Jerusalem: Who say: Rase it, rase it, even to the foundation thereof.

⁸O daughter of Babylon, miserable: blessed shall he be who shall repay thee thy payment which thou hast paid us.

⁹Blessed be he that shall take and dash thy little ones against the rock.
