Psalms 137:4

By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.

We hanged our harps upon the willows in the midst thereof.

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.

If I forget thee, O Jerusalem, let my right hand forget her cunning.
