Psalms 136:3-6

³For there they that had taken us captive asked of us the words of a song; and they that had carried us away asked a hymn, saying, Sing us one of the songs of Sion.

⁴How should we sing the Lord's song in a strange land?

⁵If I forget you, O Jerusalem, let my right hand forget its skill.

⁶May my tongue cleave to my throat, if I do not remember you; if I do not prefer Jerusalem as the chief of my joy.
