17 If a man takes his sister, his father's or his mother's daughter, and sees her nakedness and she sees his nakedness, it is a wicked and shameful thing; and they shall be cut off in the sight of their people; he has had sexual relations with his sister; he shall bear his iniquity.
18 And if a man shall lie with a woman having her menstrual pains and shall uncover her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood; and both of them shall be cut off from among their people.
19 You shall not uncover the nakedness of your mother's sister or of your father's sister, for that is to make naked his close kin; they shall bear their iniquity.
20 And if a man shall lie carnally with his uncle's wife, he has uncovered his uncle's nakedness; they shall bear their sin; they shall die childless [not literally, but in a legal sense].
21 And if a man shall take his brother's wife, it is impurity; he has uncovered his brother's nakedness; they shall be childless [not literally, but in a legal sense].
22 You shall therefore keep all My statutes and all My ordinances and do them, that the land where I am bringing you to dwell may not vomit you out [as it did those before you]. [Lev. 18:28.]
23 You shall not walk in the customs of the nation which I am casting out before you; for they did all these things, and therefore I was wearied and grieved by them.
