'Bridegroom' in the Bible

And when the headwaiter tasted the water which had turned into wine, not knowing where it came from (though the servants who had drawn the water knew) he called the bridegroom,

He who has the bride is the bridegroom; but the friend of the bridegroom, who stands by and listens to him, rejoices greatly because of the bridegroom’s voice. So this pleasure and joy of mine is now complete.
