Psalm 137:4 KJV

2We hanged our harps upon the willows in the midst thereof.

3For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion.

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

5If I forget thee, O Jerusalem, let my right hand forget her cunning.

6If I do not remember thee, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief joy.
