3 For there those who had taken us prisoners made request for a song; and those who had taken away all we had gave us orders to be glad, saying, Give us one of the songs of Zion.

Matthew Henry's Commentary on Psalm 137:3

Commentary on Psalm 137:1-4

(Read Psalm 137:1-4)

Their enemies had carried the Jews captive from their own land. To complete their woes, they insulted over them; they required of them mirth and a song. This was very barbarous; also profane, for no songs would serve but the songs of Zion. Scoffers are not to be compiled with. They do not say, How shall we sing, when we are so much in sorrow? but, It is the Lord's song, therefore we dare not sing it among idolaters.
