And the Lord spake. The prohibition of this superstition was previously expounded in its proper place. God here commands the punishment to be inflicted, if any one should have polluted himself with it. And surely it was a detestable sacrilege to enslave to idols that offspring, which was begotten to God, and which He had adopted in the loins of Abraham, since in this way they not only despoiled God of His right, but, so far as they could, blotted out the grace of adoption. What He had then generally pronounced, He now specially applies, viz., that they should be stoned who offered their seed to Molech; for otherwise they would have tried to escape on the pretense that they had no intention of revolting to other gods. Just as now-a-days, under the Papacy, whatever is alleged from Scripture against their impious and corrupt worship, is coldly and contemptuously received; because they varnish over their idolatries, and so indulge themselves in them in security. But after God has commanded His judges to punish this crime severely, He at the same time declares that, if perchance they should connive at it, and encourage it by their lenity, He Himself will avenge it, so as to punish much more heavily those who may have escaped from the hands of men; and not only so, but that He would implicate all those who might have been aware of it in the same con-detonation.

The crimes which are condemned in Leviticus. 18; 19 on purely spiritual ground, have here special punishments allotted to them as offences against the well-being of the nation.

And the Lord spake unto Moses,.... After he had delivered the above laws to him in the preceding chapter, he added penalties, to many of them, or declared what punishment should be inflicted on the transgressors of them:
saying; as follows.

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.

Punishments for the Vices and crimes Prohibited in Ch. 18 and 19. - The list commences with idolatry and soothsaying, which were to be followed by extermination, as a practical apostasy from Jehovah, and a manifest breach of the covenant.
