Leviticus 20:2

“Again thou shalt say to the children of Israel, etc.] The body of the people by their elders, and the heads of their tribes; for the following laws were binding on them all: whosoever [he be] of the children of Israel, or of the strangers that sojourn in Israel; everyone of the people of Israel, of whatsoever age, sex, or condition of life: and not they only, but the strangers and proselytes; and not the proselytes of righteousness only, but the proselytes of the gate, who, as well as the others, were to shun idolatry, and other impieties and immoralities after mentioned: that giveth [any] of his seed unto Molech; which Aben Ezra interprets of lying with an idolatrous woman, or a worshipper…”

“Molech, literally, “the King”, called also Moloch, Milcom, and Malcham, was known in later times as “the abomination of the Ammonites” 1 Kings 11:5. He appears to have been the fire-god of the eastern nations; related to, and sometimes made identical with, Baal, the sun-god. The nature of the rite and of the impious custom called passing children through the fire to Molech is very doubtful.

Molech: The Rabbins describe this idol as made of brass sitting upon a throne of the same metal, in the form of a man, with the head of a calf, adorned with a royal crown, and his arms extended as if to embrace any one. When they offered any children to him, they heated the statue by a great fire kindled within, and the victim was put into his arms, and thus consumed. Others relate, that the idol, which was hollow, was divided into…”

“Whoever, whether an Israelite or a foreigner in Israel, dedicated of his seed (children) to Moloch (see Lev 18:21), was to be put to death. The people of the land were to stone him. בּאבן רגם, lapide obruere, is synonymous with סקל, lit., lapidem jacere: this was the usual punishment appointed in the law for cases in which death was inflicted, either as the result of a judicial sentence, or by the national community. Leviticus 20:3”
