פירוש על מלכים א 21:25

But there was none likes of Achov. Scripture testifies about him that there was none among the kings like him,⁷Achov surpassed all his predecessors in doing evil. for Yerovom and all those after him worshiped the calves out of fear, that if the people would go up to Yerusholayim, the kingdom would revert to the House of Dovid, but this one added the Baal and the Asheirah to anger [God].

Sold himself. He was sold to idolatry. I saw in [Talmud] Yerushalmi that Chieil from the house of Eili was his advisor, and every day he would estimate his value and give it to the pagan deities.⁸Talmud Yerushalmi Maseches Sanhedrin 10:2.
