Ahaz was twenty years old when he began to reign,.... These verses are much the same with Kg2 16:2, only in Ch2 28:2 it is said, he made also molten images for Baalim; the several Baals or idols of the nations round about, as well as served Jeroboam's calves; see Jdg 2:11, and he is said in Ch2 28:3, to burn incense in the valley of the son of Hinnom; to Molech, the god of the Ammonites, who was worshipped there. See Gill on Kg2 16:2, Kg2 16:3, Kg2 16:4.
