1 By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.
2 We hanged our harps upon the willows in the midst thereof.
3 For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion.
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.
8 O daughter of Babylon, who art to be destroyed; happy shall he be, that rewardeth thee as thou hast served us.
You Babylonians will be rewarded for the way you treated us.
9Happy shall he be, that taketh and dasheth thy little ones against the stones
Famously, a portion of this was set to music by Brent Dowe and Trevor McNaughton of the Jamaican reggae group The Melodians, and later famously recorded by Bob Marley. However, they left out the part about smashing babies against the rocks.
