Leviticus 18:7-9

Modern English Version

⁷ You shall not have relations with your father or have relations with your mother. She is your mother. You shall not have relations with her.

⁸ You shall not have relations with your father’s wife, for this exposes your father’s nakedness.

⁹ You shall not have relations with your sister, whether your father’s or mother’s daughter, whether raised in the family or another home.
