Tehillim 137:4-6

Orthodox Jewish Bible

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

⁵ If I forget thee, O Yerushalayim, let my yamin (right hand) forget [i.e., have paralysis].

⁶ If I do not remember thee, let my leshon cleave to the roof of my mouth; if I prefer not Yerushalayim above my rosh simchah (chief joy).
