Leviticus 20:21-23

New Catholic Bible

²¹ It is unclean for a man to marry his brother’s wife for he shall have uncovered his brother’s nakedness. They shall be childless.

²² “ ‘You shall therefore observe all of my statutes and ordinances and obey them, so that the land to which I am bringing you to dwell in will not vomit you out. ²³ You shall not follow the ways of the nations that I cast out before you for having done all these things that I abhorred.
