'Companion' in the Bible

And Gideon cometh in, and lo, a man is recounting to his companion a dream, and saith, 'Lo, a dream I have dreamed, and lo, a cake of barley-bread is turning itself over into the camp of Midian, and it cometh in unto the tent, and smiteth it, and it falleth, and turneth it upwards, and the tent hath fallen.'

And his companion answereth and saith, 'This is nothing save the sword of Gideon son of Joash, a man of Israel; God hath given into his hand Midian and all the camp.'

and the three hundred blow the trumpets, and Jehovah setteth the sword of each against his companion, even through all the camp; and the camp fleeth unto Beth-Shittah, at Zererath, unto the border of Abel-Meholah, by Tabbath.

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 answered, Samson, the son in law of the Timnite, because he had taken his wife, and given her to his companion. And the Philistines came up, and burnt her and her father with fire.
