Leviticus 20:19

17 If a man marries his sister, whether the daughter of his father or of his mother, and they have sexual relations, it is a disgrace. They must be cut off in the sight of their people. He has uncovered the nakedness of his sister; he shall bear his iniquity.

18 If a man lies with a menstruating woman and has sexual relations with her, he has exposed the source of her flow, and she has uncovered the source of her blood. Both of them must be cut off from among their people.

You must not have sexual relations with the sister of your mother or your father, for it is exposing one’s own kin; both shall bear their iniquity.

20 If a man lies with his uncle’s wife, he has uncovered the nakedness of his uncle. They will bear their sin; they shall die childless.

21 If a man marries his brother’s wife, it is an act of impurity. He has uncovered the nakedness of his brother; they shall be childless.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
