'Companion' in the Bible

But Samson’s wife was given to his companion who had been his friend.

Her father said, “I really thought that you hated her intensely; so I gave her to your companion. Is not her younger sister more beautiful than she? Please let her be yours instead.”

Then the Philistines said, “Who did this?” And they said, “Samson, the son-in-law of the Timnite, because he took his wife and gave her to his companion.” So the Philistines came up and burned her and her father with fire.
