Leviticus 18:10-14

The nakedness of thy son’s daughter, or of thy daughter’s daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.

The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.

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

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

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