Leviticus 20:19

You shall not uncover the nakedness of your mother’s sister or of your father’s sister, for that is to make naked one’s relative; they shall bear their iniquity.

“ ‘Do not have sexual relations with the sister of either your mother or your father, for that would dishonor a close relative; both of you would be held responsible.

You must not have sexual intercourse with your mother’s sister or your father’s sister, for it is exposing one’s own blood relative; both people will bear their iniquity.

“Do not have sexual relations with your aunt, whether your mother’s sister or your father’s sister. This would dishonor a close relative. Both parties are guilty and will be punished for their sin.

And you shall not expose the nakedness of your mother’s sister, and you shall not expose your father’s sister, because such a person has dishonored his close relative—they must bear their guilt.

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.
