Leviticus 18:6-8

International Standard Version

⁶ “A person is not to approach a near blood relative for sexual relations.^[a] I am the Lord.

⁷ “Neither your father’s nakedness nor your mother’s nakedness is to be exposed. She’s your mother, so you are not to have sexual relations with her.

⁸ “You are not to have sexual relations with your father’s wife. It’s your own father’s nakedness.
