Leviticus 18:17-19

New Life Version

¹⁷ Do not take the clothes off a woman and her daughter. And do not take the clothes off her son’s daughter or her daughter’s daughter. They are of her own family. It is sin. ¹⁸ While your wife is still living do not marry her sister making her as important to you. Do not take off her sister’s clothes.

¹⁹ ‘And you are not to go near a woman to take off her clothes during the time when she has a flow of blood.
