'Rejoice' in the Bible

if ye then have dealt truly and uprightly with Jerubbaal and with his house this day, then rejoice ye in Abimelech, and let him also rejoice in you:

And the lords of the Philistines gathered them together to offer a great sacrifice unto Dagon their god, and to rejoice; for they said, Our god hath delivered Samson our enemy into our hand.
