'Bridegroom' in the Bible

Now when the head steward tasted the water which had become wine and did not know where it was from--but the servants who had drawn the water knew--the head steward summoned the bridegroom

The one who has the bride is the bridegroom. But the friend of the bridegroom, who stands and hears him, rejoices {greatly} because of the bridegroom's voice. So this joy of mine is complete.
