Friday slowdown

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? (Psalm 137:1-4)
