Leviticus 18:15

12 Thou shalt not uncover the nakedness of thy father`s sister: she is thy father`s near kinswoman.

13 Thou shalt not uncover the nakedness of thy mother`s sister: for she is thy mother`s near kinswoman.

14 Thou shalt not uncover the nakedness of thy father`s brother, thou shalt not approach to his wife: she is thine aunt.

15 Thou shalt not uncover the nakedness of thy daughter-in-law: she is thy son`s wife; thou shalt not uncover her nakedness.

16 Thou shalt not uncover the nakedness of thy brother`s wife: it is thy brother`s nakedness.

17 Thou shalt not uncover the nakedness of a woman and her daughter; thou shalt not take her son`s daughter, or her daughter`s daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.

18 And thou shalt not take a wife to her sister, to be a rival [to her], to uncover her nakedness, besides the other in her life-time.
