'Bridegroom's' in the Bible

"Can the bridegroom's party mourn," He replied, "as long as the bridegroom is with them? But other days will come (when the Bridegroom has been taken from them)

He who has the bride is the bridegroom; and the bridegroom's friend who stands by his side and listens to him, rejoices heartily on account of the bridegroom's happiness. Therefore this joy of mine is now complete.
