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.
