17 And if a man takes his sister, daughter of his father or his mother, and has sex relations with her and she with him, it is an act of shame: they are to be cut off before the children of their people; he has had sex relations with his sister, and his sin will be on him.
18 And if a man has sex relations with a woman at the time when she is unwell, he has seen her fountain and she has let the fountain of her blood be uncovered, and the two of them are to be cut off from among their people.
19 And you may not have sex connection with your mother's sister or your father's sister, for they are his near relations: their sin will be on them.
20 And if a man has sex relations with the wife of his father's brother, he has put shame on his father's brother: their sin will be on them; till the day of their death they will have no children.
21 And if a man takes his brother's wife, it is an unclean act; he has put shame on his brother; they will have no children.

Commentary on Leviticus 20 Matthew Henry Commentary
Chapter 20
The laws which before were made are in this chapter repeated and penalties annexed to them, that those who would not be deterred from sin by the fear of God might be deterred from it by the fear of punishment. If we will not avoid such and such practices because the law has made them sin (and it is most acceptable when we go on that principle of religion), surely we shall avoid them when the law has made them death, from a principle of self-preservation. In this chapter we have,
Lev 20:1-9
Moses is here directed to say that again to the children of Israel which he had in effect said before, v. 2. We are sure it was no vain repetition, but very necessary, that they might give the more earnest heed to the things that were spoken, and might believe them to be of great consequence, being so often inculcated. God speaketh once, yea, twice, and what he orders to be said again we must be willing to hear again, because for us it is safe, Phil. 3:1.
Lev 20:10-21
Sins against the seventh commandment are here ordered to be severely punished. These are sins which, of all others, fools are most apt to make a mock at; but God would teach those the heinousness of the guilt by the extremity of the punishment that would not otherwise be taught it.
Lev 20:22-27
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, v. 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:-
