Parallel
Leviticus 18:7
Brenton's English Septuagint · Berean Standard Bible
Thou shalt not uncover the nakedness of thy father, or the nakedness of thy mother, for she is thy mother; thou shalt not uncover her nakedness.
You must not expose the nakedness of your father by having sexual relations with your mother. She is your mother; you must not have sexual relations with her.
