Psalms (Author Moses, David, Solomon, Asaph, Heman, Ethan, sons of Korah, compiled by Ezra)
137:1By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.
137:3For 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.
