Leviticus 18:5-7

Darby Translation

⁵ And ye shall observe my statutes and my judgments, by which the man that doeth them shall live: I am Jehovah.

⁶ No one shall approach to any that is his near relation, to uncover his nakedness: I am Jehovah.

⁷ The nakedness of thy father, and the nakedness of thy mother, shalt thou not uncover: she is thy mother: thou shalt not uncover her nakedness.
