Psalms 137:3-6

³For those who had taken us captive asked us for a song—our tormentors wanted us to sing a happy song from Jerusalem.

⁴But how could we sing a song dedicated to the Lord in a pagan land?

⁵If I forget Jerusalem, may my right hand forget how to play;

⁶May my tongue stick to the roof of my mouth if I don't remember you—if I don't consider Jerusalem my greatest joy.
