'Bridegroom' in the Bible

When the head steward tasted the water that had been turned to wine, not knowing where it came from (though the servants who had drawn the water knew), he called the bridegroom

The one who has the bride is the bridegroom. The friend of the bridegroom, who stands by and listens for him, rejoices greatly when he hears the bridegroom's voice. This then is my joy, and it is complete.
