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.
Jeremiah 7:31
29 So mourn, you people of this nation. Cut off your hair and throw it away. Sing a song of mourning on the hilltops. For the Lord has decided to reject and forsake this generation that has provoked his wrath!’” 30 The Lord says, “I have rejected them because the people of Judah have done what I consider evil. They have set up their disgusting idols in the temple that I have claimed for my own and have defiled it. 31 They have also built places of worship in a place called Topheth in the Valley of Ben Hinnom so that they can sacrifice their sons and daughters by fire. That is something I never commanded them to do! Indeed, it never even entered my mind to command such a thing! 32 So, watch out!” says the Lord. “The time will soon come when people will no longer call those places Topheth or the Valley of Ben Hinnom. But they will call that valley the Valley of Slaughter, and they will bury so many people in Topheth that they will run out of room. 33 Then the dead bodies of these people will be left on the ground for the birds and wild animals to eat. There will not be any survivors to scare them away.
Notes and References
"... The divine recipients of the mlk sacrifice vary within the same cultures. In Israel mlk in Jeremiah 19:5 and 32:35 (compare 2 Kings 17:16-17) is a term for a human sacrifice intended allegedly for Baal. Psalm 106:34-38 attributes child sacrifice to Baal Peor. According to 2 Kings 17:31 the Sepharvites devoted child sacrifice to two gods, Adrammelek and Anammelek. Jeremiah 7:31; 19:5, and 32:35 deny that mlk sacrifice was offered in Yahweh’s name; these denials may suggest that offering this sacrifice in Yahweh’s name occurred (compare Leviticus 18:21; 20:3; Genesis 22) ... Isaiah 30:27-33 appears as the best evidence for the early practice of child sacrifice in Israel. According to Mosca, the image of child sacrifice in this eighth or seventh century passage serves as a way to describe Yahweh’s coming destruction of Israel. In this text there is no offense taken at the Tophet, the precinct of child sacrifice. It would appear that Jerusalemite cult included child sacrifice under Yahwistic patronage; it is this that Leviticus 20:2-5 deplores. Ezekiel 16:20, 21, 36 and 23:39 assume that child sacrifice was intended for a multiplicity of deities. The legal proscriptions against child sacrifice in the Holiness Code (Leviticus 18:21; 20:2-5) and in Deuteronomy 12:31 and 18:10 are unclear regarding the divine recipients. Leviticus 20:2-5 suggests that this sacrifice is not to take place in Yahweh’s temple, perhaps to avoid performance of it in his name ..."
