Midrasch zu Wajikra 20:3

1) (Vayikra 16:16) ("And he shall make atonement for the holy place from the uncleanlinesses of the children of Israel, and from their offenses of all of their sins; and so shall he do for the tent of meeting that dwells with them in the midst of their uncleanlinesses.") "And he shall make atonement for the holy place from the uncleanlinesses of the children of Israel": Three "uncleanlinesses" may be adduced here: that of idolatry, viz. (Vayikra 20:3) ("for of his seed he has given to the Molech) to defile My Sanctuary and to profane My holy name"; that of illicit relations, viz. (Vayikra 18:30) "not to do in the manner of the abominations that were done before you, and you shall not become unclean in them"; that of bloodshed, viz. (Bamidbar 35:34) "And you shall not defile the land wherein you dwell, in whose midst I dwell."

5) (Vayikra 20:3) ("And I will set My face against that man, and I will cut him off from the midst of his people; for of his seed he has given to the Molech, to defile My sanctuary and to profane My holy name.") "And I will set My face (panai)": I will "free myself (poneh ani [similar to panai]) from all of My "affairs," and occupy Myself entirely with him. "against that man": and not against the congregation. "that man": and not one who is constrained, or unwitting, or mistaken. "and I will cut him off from the midst of his people": But his people will remain at peace.

6) "for of his seed he has given to the Molech": What is the intent of this? Because it is written (Devarim 18:10) "There shall not be found among you one who passes his son or daughter through fire," I might think only his son or daughter. Whence do I derive (for inclusion) the daughter of his son and the son of his daughter? From "for of his seed he has given to the Molech."
