'Rejoice' in the Bible

Wherein ye greatly rejoice, though now for a season, if need be, ye are in heaviness through manifold temptations:

Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory:

But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.
