Leviticus 20:19

¹⁷Whosoever shall take his sister by his father or by his mother, and shall see her nakedness, and she see his nakedness, it is a reproach: they shall be destroyed before the children of their family; he has uncovered his sister’s nakedness, they shall bear their sin.

¹⁸And whatever man shall lie with a woman that is set apart for a flux, and shall uncover her nakedness, he has uncovered her fountain, and she has uncovered the flux of her blood: they shall both be destroyed from among their generation.

— Leviticus 20:19 —

²⁰Whosoever shall lie with his near kinswoman, has uncovered the nakedness of one near akin to him: they shall die childless.

²¹Whoever shall take his brother’s wife, it is uncleanness; he has uncovered his brother’s nakedness; they shall die childless.
