Leviticus 20:19

And thou shalt not uncover the nakedness of thy mother's sister, nor of thy father's sister: for he uncovereth his near kin: they shall bear their iniquity.

"'You shall not uncover the nakedness of your mother's sister, nor of your father's sister; for he has made naked his close relative: they shall bear their iniquity.

And thou shalt not uncover the nakedness of thy mother's sister, nor of thy father's sister; for he hath made naked his near kin: they shall bear their iniquity.

`And the nakedness of thy mother's sister, and of thy father's sister, thou dost not uncover; because his relation he hath made bare; their iniquity they bear.

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.
