'Companion' in the Bible

And Samson's wife was given to his companion, who had been his best man.

And her father said, "I really thought that you utterly hated her; so I gave her to your companion. Is not her younger sister fairer than she? Pray take her instead."

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