“For 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.”
King James Version (KJV)
Matthew Henry's Concise Commentary
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.
“There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband.”
