'Bridegroom' in the Bible

When the ruler of the feast tasted the water now become wine, and didn't know where it came from (but the servants who had drawn the water knew), the ruler of the feast called the bridegroom,

He 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. This, my joy, therefore is made full.
