'Vanities' in the Bible

concerning all the sins of Baasha, and the sins of Elah his son, that they sinned, and that they caused Israel to sin to provoke Jehovah, God of Israel, with their vanities.

and walketh in all the way of Jeroboam son of Nebat, and in his sin that he caused Israel to sin, to provoke Jehovah, God of Israel, with their vanities.
