Psalm 137:7-9

New Revised Standard Version, Anglicised Catholic Edition

⁷ Remember, O Lord, against the Edomites
    the day of Jerusalem’s fall,
how they said, ‘Tear it down! Tear it down!
    Down to its foundations!’
⁸ O daughter Babylon, you devastator!^[a]
    Happy shall they be who pay you back
    what you have done to us!
⁹ Happy shall they be who take your little ones
    and dash them against the rock!
