'Chorus' in the Bible

when the morning stars sang in chorus, and all the sons of God shouted for joy?

Let them praise His name with dancing;Let them sing praises to Him with the tambourine and lyre.

As the chorus of 'Mahanaim.' How beautiful were thy feet with sandals, O daughter of Nadib. The turnings of thy sides are as ornaments, Work of the hands of an artificer.

Again do I build thee, And thou hast been built, O virgin of Israel, Again thou puttest on thy tabrets, And hast gone out in the chorus of the playful.

Then rejoice doth a virgin in a chorus, Both young men and old men -- together, And I have turned their mourning to joy, And have comforted them, And gladdened them above their sorrow,
