The Covenant Collision

"By the rivers of Babylon, there we sat down, yea, we wept when we remembered Zion. We hung our harps upon the willows in the midst of it. For there those who carried us away captive asked of us a song, and those who plundered us requested mirth, saying, “Sing us one of the songs of Zion!” How shall we sing the Lord’s song in a foreign land?"
(Psalm 137:1-4)
