2 Kings 16:3-5

Complete Jewish Bible

³ Rather, he lived in the manner of the kings of Isra’el; he even made his son pass through fire [as a sacrifice], in keeping with the abominable practices of the pagans, whom Adonai had thrown out ahead of the people of Isra’el. ⁴ He also sacrificed and offered on the high places, on the hills and under any green tree.

⁵ Then Retzin king of Aram and Pekach son of Remalyah, king of Isra’el, came up to fight against Yerushalayim. They put Achaz under siege, but they could not overcome him.
