Leviticus 18:12-15

¹²Do not sleep with your father's sister. She is a close relative to your father.

¹³Do not sleep with your mother's sister. She is a close relative to your mother.

¹⁴Do not dishonor the brother of your father by sleeping with his wife. Do not go near her for that purpose; she is your aunt.

¹⁵Do not sleep with your daughter-in-law. She is your son's wife; do not sleep with her.
