By the rivers of Babylon we sat and wept when we remembered Zion.There on the poplars we hung our harps, for there our captors asked us for songs, our tormentors demanded songs of joy; they said,“Sing us one of the songs of Zion!”How can we sing the songs of the Lord while in a foreign land? If I forget you, O Jerusalem, may my right hand forget its skill. —PSALM 137:1–5
