And it will be at the time of the old age of Solomon his wives turned away his heart after other gods: and his heart was not perfect with Jehovah his God as the heart of David his father. And Solomon will go after Ashtaroth the god of the Zidonians, and after Milcom the abomination of the Ammonites.
