Tehillim 137:2-4

Orthodox Jewish Bible

² We hung up our kinnorot (lyres) upon the willows in the midst thereof.

³ For there they that carried us away captive required of us a shir (song); and they that tormented us required of us simchah, saying, Sing us one of the Shir Tziyon.

⁴ How shall we sing Shir Hashem in an admat nekhar (foreign land).
