The last verse is a particular law, which comes in after the general conclusion, as if omitted in its proper place: it is for the putting of those to death that dealt with familiar spirits, Lev 20:27. It would be an affront to God and to his lively oracles, a scandal to the country, and a temptation to ignorant bad people, to consult them, if such were known and suffered to live among them. Those that are in league with the devil have in effect made a covenant with death and an agreement with hell, and so shall their doom be.

The rest of these verses repeat and inculcate what had been said before; for to that unthinking forgetful people it was requisite that there should be line upon line, and that general rules, with their reasons, should be frequently insisted on, for the enforcement of particular laws, and making them more effectual. Three things we are here reminded of:-

I.Their dignity. 1. They had the Lord for their God, Lev 20:24. They were his, his care, his choice, his treasure, his jewels, his kingdom of priests (Lev 20:26): That you should be mine. Happy the people, and truly great, that are in such a case. 2. Their God was a holy God (Lev 20:26), infinitely advanced above all others. His holiness is his glory, and it was their honour to be related to him, while their neighbours were the infamous worshippers of impure and filthy spirits. 3. The great God had separated them from other people (Lev 20:24), and again, Lev 20:26. Other nations were the common; they were the enclosure, beautified and enriched with peculiar privileges, and designed for peculiar honours; let them therefore value themselves accordingly, preserve their honour, and not lay it in the dust, by walking in the way of the heathen.

II.Their duty; this is inferred from their dignity. God had done more for them than for others, and therefore expected more from them than from others. And what is it that the Lord their God requires, in consideration of the great things done and designed? 1. You shall keep all my statutes (Lev 20:22); and there was all the reason in the world that they should, for the statutes were their honour, and obedience to them would be their lasting comfort. 2. You shall not walk in the manners of nations, Lev 20:23. Being separated from them, they must not associate with them, nor learn their ways. The manners of the nations were bad enough in them, but would be much worse in God's people. 3. You shall put a difference between clean and unclean, Lev 20:25. This is holiness, to discern between things that differ, not to live at large, as if we might say and do any thing, but to speak and act with caution. 4. You shall not make your souls abominable, Lev 20:25. Our constant care must be to preserve the honour, by preserving the purity, of our own souls, and never to do any thing to make them abominable to God and to our own consciences.

III.Their danger. 1. They were going into an infected place (Lev 20:24): You shall inherit their land, a land flowing with milk and honey, which they would have the comfort of if they kept their integrity; but, withal, it was a land full of idols, idolatries, and superstitious usages, which they would be apt to fall in love with, having brought from Egypt with them a strange disposition to take that infection. 2. If they took the infection, it would be of pernicious consequence to them. The Canaanites were to be expelled for these very sins: They committed all these things, therefore I abhorred them, Lev 20:23. See what an evil thing sin is; it provokes God to abhor his own creatures, whereas otherwise he delights in the work of his hands. And, if the Israelites trod in the steps of their impiety, they must expect that the land would spue them out (Lev 20:22), as he had told them before, Lev 18:28. If God spared not the natural branches, but broke them off, neither would he spare those who were grafted in, if they degenerated. Thus the rejection of the Jews stands for a warning to all Christian churches to take heed lest the kingdom of God be taken from them. Those that sin like others must expect to smart like them; and their profession of relation to God will be no security to them.

The land, whither I bring you to dwell therein, spue you not out - See this energetic prosopopoeia explained in the note on Lev 18:25 (note). From this we learn that the cup of the iniquities of the Canaanitish nations was full; and that, consistently with Divine justice, they could be no longer spared.

Ye shall therefore keep all my statutes,.... All the ordinances, institutions, and appointments of God, whether observed in this chapter or elsewhere, but particularly those concerning incestuous marriages and unlawful copulations:

and all my judgments, and do them; all the laws and commandments of God, founded injustice and judgment, and according to the rules thereof; or else, as Aben Ezra, the judgments of punishment, or the penalties annexed to the above laws, which were carefully to be observed, and put into execution, to deter from the transgression of them:

that the land, whither I bring you to dwell therein, spew you not out; as the stomach does its food when it is loathsome and nauseous to it, and it cannot bear it; see Lev 18:25.

they shall die childless--Either by the judgment of God they shall have no children, or their spurious offspring shall be denied by human authority the ordinary privileges of children in Israel.
