'Companion' in the Bible

and his servants say to him, 'Let them seek for my lord the king a young woman, a virgin, and she hath stood before the king, and is to him a companion, and hath lain in thy bosom, and my lord the king hath heat.'

and the young woman is very very fair, and she is to the king a companion, and serveth him, and the king hath not known her.
