how shall we sing the lord's song in a foreign land?

let my tongue [cling] to the roof of my mouth, if i remember thee not; if i set not jerusalem above my chiefest joy.

—psalm 137, verses 4-6

what does this passage show about jews during the babylonian captivity?

they felt happy to be in a new country.
