'Companion' in the Bible

And Samson's wife was [given] to his companion who [was] his best man.

Her father said, "I really thought that you hated her, so I gave her to your companion. [Is] not her younger sister more beautiful than she? Please, {take her instead}."

And [the] Philistines said, "Who has done this?" And they said, "Samson the son-in-law of the Timnite, because he took his wife and gave her to his companion." And [the] Philistines went up and burned her and her father with fire.
