Leviticus 18:16-18

New International Version - UK

¹⁶ ‘“Do not have sexual relations with your brother’s wife; that would dishonour your brother.

¹⁷ ‘“Do not have sexual relations with both a woman and her daughter. Do not have sexual relations with either her son’s daughter or her daughter’s daughter; they are her close relatives. That is wickedness.
