'Serveth' in the Bible

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.

And it cometh to pass -- hath it been light his walking in the sins of Jeroboam son of Nebat? -- then he taketh a wife, Jezebel daughter of Ethbaal, king of the Zidonians, and goeth and serveth Baal, and boweth himself to it,

And he turneth back from after him, and taketh the yoke of oxen, and sacrificeth it, and with instruments of the oxen he hath boiled their flesh, and giveth to the people, and they eat, and he riseth, and goeth after Elijah, and serveth him.

and serveth the Baal, and boweth himself to it, and provoketh Jehovah, God of Israel, according to all that his father had done.
