'Companion' in the Bible

But Samson's wife was given to his companion, whom he had used as his friend.

And her father said, I verily thought that thou hadst utterly hated her; therefore I gave her to thy companion: is not her younger sister fairer than she? take her, I pray thee, instead of her.

Then the Philistines said, Who hath done this? And they said, Samson, the son-in-law of the Timnite, because he hath taken his wife, and given her to his companion. And the Philistines came up, and burnt her and her father with fire.
