Psalms 137:9 WEB

⁷  Remember, Yahweh, against the children of Edom, The day of Jerusalem; Who said, 'Raze it! Raze it even to its foundation!'

⁸  Daughter of Babylon, doomed to destruction, He will be happy who rewards you, As you have served us.

⁹  Happy shall he be, Who takes and dashes your little ones against the rock.
