2 Chronicles 28:2-4

28:2 He followed in the footsteps of the kings of Israel; he also made images of the Baals. 28:3 He offered sacrifices in the Valley of Ben-Hinnom and passed his sons through the fire, a horrible sin practiced by the nations whom the Lord drove out before the Israelites. 28:4 He offered sacrifices and burned incense on the high places, on the hills, and under every green tree.

2 Chronicles 28:23-25

28:23 He offered sacrifices to the gods of Damascus whom he thought had defeated him. He reasoned, “Since the gods of the kings of Damascus helped them, I will sacrifice to them so they will help me.” But they caused him and all Israel to stumble. 28:24 Ahaz gathered the items in God’s temple and removed them. He shut the doors of the Lord’s temple and erected altars on every street corner in Jerusalem. 28:25 In every city throughout Judah he set up high places to offer sacrifices to other gods. He angered the Lord God of his ancestors.
