In the Bible, God talks about the Israelites having their sons and daughters “pass through the fire”. Some people say that this was just a ceremonial thing, and did not involve child sacrifice.
One of the things that is said is this is the same as “walking the fire” or “fire walking” as evidenced in this National Geographic article.
So, “passing through the fire” would simply be a ritual of becoming an adult, maybe, or just some type of ceremony.
Except it isn’t.
In the Book of Ezekiel, chapter 23, God is judging Israel and Judah for their worship of demons and human sacrifice. In verses 36-39 we read one of the reasons for their destruction:
“The LORD said moreover unto me; Son of man, wilt thou judge Aholah and Aholibah? yea, declare unto them their abominations; That they have committed adultery, and blood is in their hands, and with their idols have they committed adultery, and have also caused their sons, whom they bare unto me, to pass for them through [the fire,] to devour [them.] Moreover this they have done unto me: they have defiled my sanctuary in the same day, and have profaned my sabbaths. For when they had slain their children to their idols, then they came the same day into my sanctuary to profane it; and, lo, thus have they done in the midst of mine house.”
And who did they sacrifice their children to in the fire?
“And thou shalt not let any of thy seed pass through [the fire] to Molech, neither shalt thou profane the name of thy God:” — Leviticus 18:21
Molech, the [g]od that children were sacrificed to, is a demon-god that took the form after the worship of Nimrod, who first instituted fire sacrifice after the flood, when he also attempted to sacrifice Abraham in the fire:
“The author of the “Ta’rikh Muntaḥab” (quoted by D’Herbelot in his “Bibliothèque Orientale”) identifies Nimrod with Daḥḥak (the Persian Zoḥak), the first Persian king after the Flood. But Al-Kharizmi (“Mafatiḥ al-‘Ulum,” quoted by D’Herbelot) identifies him with Kai Kaos, the second king of the second Persian dynasty. Nimrod reigned where Bagdad is now situated, and at first he reigned with justice (see Nimrod in Rabbinical Literature); but Satan perverted him, and then he began to persecute all the worshipers of God. His chief vizier was Azar (Terah), the father of Abraham; and the midrashic legends of Abraham’s birth in which Nimrod is mentioned, as well as those concerning Nimrod’s persecution of Abraham—whom he cast into a furnace—are narrated also by the Mohammedans (see Abraham in Apocryphal and Rabbinical Literature and in Mohammedan Legend).” — from the Jewish Encylopedia
So, let’s all be clear on this: The act of making ones children “pass through the fire” was simple and horrific: Human child sacrifice to the devil god Molech.
The people had no excuse; they were told from the time of Moses not to do this thing, and yet they did.
