4How shall we sing the LORD'S song in a foreign land?
5If I forget thee, O Jerusalem, let my right hand forget her cunning.
6Let my tongue cleave to the roof of my mouth, if I remember thee not; if I set not Jerusalem above my chiefest joy.
7Remember, O LORD, against the children of Edom the day of Jerusalem; who said: 'Rase it, rase it, even to the foundation thereof.'
8O daughter of Babylon, that art to be destroyed; happy shall he be, that repayeth thee as thou hast served us.
9Happy shall he be, that taketh and dasheth thy little ones against the rock.
