Leviticus 20:7; Leviticus 20:10; Leviticus 20:17
" 'Consecrate yourselves and be holy, because I am the LORD your God.
" 'If a man commits adultery with another man's wife--with the wife of his neighbor--both the adulterer and the adulteress must be put to death.
" 'If a man marries his sister, the daughter of either his father or his mother, and they have sexual relations, it is a disgrace. They must be cut off before the eyes of their people. He has dishonored his sister and will be held responsible.
