Parallel
Leviticus 20:19
Brenton's English Septuagint · Berean Standard Bible
And thou shalt not uncover the nakedness of thy father's sister, or of the sister of thy mother; for that man has uncovered the nakedness of one near akin: they shall bear their iniquity.
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.
