Deuteronomy 18:10
8 He must eat the same share they do, despite any profits he may gain from the sale of his family’s inheritance. 9 When you enter the land the Lord your God is giving you, you must not learn the abhorrent practices of those nations. 10 There must never be found among you anyone who sacrifices his son or daughter in the fire, anyone who practices divination, an omen reader, a soothsayer, a sorcerer, 11 one who casts spells, one who conjures up spirits, a practitioner of the occult, or a necromancer. 12 Whoever does these things is abhorrent to the Lord, and because of these detestable things the Lord your God is about to drive them out from before you.
Ezekiel 20:31
29 So I said to them, “What is this high place you go to?”’ (So it is called “High Place” to this day.) 30 “Therefore say to the house of Israel, ‘This is what the Sovereign Lord says: Will you defile yourselves like your fathers and engage in prostitution with detestable idols? 31 When you present your sacrifices—when you make your sons pass through the fire—you defile yourselves with all your idols to this very day. Will I allow you to seek me, O house of Israel? As surely as I live, declares the Sovereign Lord, I will not allow you to seek me! 32 “‘What you plan will never happen. You say, “We will be like the nations, like the clans of the lands, who serve gods of wood and stone.” 33 As surely as I live, declares the Sovereign Lord, with a powerful hand and an outstretched arm and with an outpouring of rage, I will be king over you.
Notes and References
"... “And he, he caused his sons to pass through the fire in the Valley of Ben-Hinnom” (2 Chronicles 33:6). Passing one’s son or daughter through fire is expressly prohibited in the laws of Deuteronomy (18:10). Commonly thought to involve some sort of child sacrifice, the practice is only mentioned a few times in the Deuteronomistic history of the dual monarchies. (Compare Deuteronomy 18:10; 2 Kings 16:3; Ezekiel 20:31) It should be noted that Chronicles does not mention a similar (irregular) attempt to procure divine favor (by the Moabite king), during a joint northern-southern military expedition (2 Kings 3:4-27). Manasseh is only one of two Judahite kings charged with this particular type of malfeasance. The other is Ahaz who, like Manasseh, is guilty (in Chronicles) of passing his sons (not simply “son”) through fire (2 Chronicles 28:3). In this case, there are two other differences with the source text of Kings that require commentary. The text of 2 Kings 21:6 lacks the third masculine singular personal pronoun, which emphasizes the subject (Manasseh) as the originator of the action described. 2 Kings 21:6 also lacks the geographical descriptor “in the Valley of Ben-Hinnom.” The mention of the location intensifies the parallel with Ahaz (2 Chronicles 28:3), who is viewed by the Chronicler as the worst king in Judahite history (2 Chronicles 28:22-25) ..."
