'Captives' in the Bible

O Lord, You have [at last] shown favor to Your land [of Canaan];You have restored [from Babylon] the captives of Jacob (Israel).

When the Lord brought back the captives to Zion (Jerusalem),We were like those who dream [it seemed so unreal].

By the rivers of Babylon,There we [captives] sat down and wept,When we remembered Zion [the city God imprinted on our hearts].
