Leviticus 18:10-12

Amplified Bible

¹⁰ You shall not uncover the nakedness of your son’s daughter or your daughter’s daughter; their nakedness you shall not uncover, for they are your own nakedness [that is, your own descendants]. ¹¹ You shall not uncover the nakedness of your father’s wife’s daughter; born to your father, she is your sister. ¹² You shall not uncover the nakedness of your father’s sister; she is your father’s blood relative.
