And you shall not let any of your seed pass through l'Molech, neither shall you profane the name of your God: I am the Lord.…Again, you shall say to the Sons of Israel: Whoever he be of the Sons of Israel or of the strangers that sojourn in Israel, that gives any of his seed l'Molech; he shall surely be put to death: the people of the land shall stone him with stones. And I will set my face against that man and will cut him off from among his people; because he has given of his seed l'Molech, to defile my sanctuary, and to profane my holy name. And if the people of the land do at all hide their eyes from that man, when he gives of his seed l'Molech, and do not kill him, then I will set my face against that man, and against his family, and will cut him off, and all that go astray after him, whoring l'Molech from among the people.
––Leviticus 18:21 and 20:2-5.
Most of us have learned midrashim and aggadata that echo and expand on this theme.
In other words, as Science Daily notes under the headline, Study Debunks Millennia-Old Claims of Systematic Infant Sacrifice in Ancient Carthage:
"Our study emphasizes that historical scientists must consider all evidence when deciphering ancient societal behavior," Schwartz said. "The idea of regular infant sacrifice in Carthage is not based on a study of the cremated remains, but on instances of human sacrifice reported by a few ancient chroniclers, inferred from ambiguous Carthaginian inscriptions, and referenced in the Old Testament. Our results show that some children were sacrificed, but they contradict the conclusion that Carthaginians were a brutal bunch who regularly sacrificed their own children."
…Schwartz and his colleagues conclude that the high incidence of prenate and infant mortality are consistent with modern data on stillbirths, miscarriages, and infant death.
An examination of the remains of Carthaginian children revealed that most infants perished prenatally or very shortly after birth and were unlikely to have lived long enough to be sacrificed.
