2 'And unto the sons of Israel thou dost say, Any man of the sons of Israel, and of the sojourners who is sojourning in Israel, who giveth of his seed to the Molech, is certainly put to death; the people of the land do stone him with stones; 3 and I—I set My face against that man, and have cut him off from the midst of his people, for of his seed he hath given to the Molech, so as to defile My sanctuary, and to pollute My holy name. 4 'And if the people of the land really hide their eyes from that man, in his giving of his seed to the Molech, so as not to put him to death, 5 then I have set My face against that man, and against his family, and have cut him off, and all who are going a-whoring after him, even going a-whoring after the Molech, from the midst of their people.

Matthew Henry's Commentary on Leviticus 20:2-5

Commentary on Leviticus 20:1-9

(Read Leviticus 20:1-9)

Are we shocked at the unnatural cruelty of the ancient idolaters in sacrificing their children? We may justly be so. But are there not very many parents, who, by bad teaching and wicked examples, and by the mysteries of iniquity which they show their children, devote them to the service of Satan, and forward their everlasting ruin, in a manner even more to be lamented? What an account must such parents render to God, and what a meeting will they have with their children at the day of judgment! On the other hand, let children remember that he who cursed father or mother was surely put to death. This law Christ confirmed. Laws which were made before are repeated, and penalties annexed to them. If men will not avoid evil practices, because the law has made these practices sin, and it is right that we go on that principle, surely they should avoid them when the law has made them death, from a principle of self-preservation. In the midst of these laws comes in a general charge, Sanctify yourselves, and be ye holy. It is the Lord that sanctifies, and his work will be done, though it be difficult. Yet his grace is so far from doing away our endeavours, that it strongly encourages them. Work out your salvation, for it is God that worketh in you.
