If a person who was unclean ate the peace offering, he was to be “cut off” (krt) from his people. This is the first occurrence of the krt penalty in the book of Leviticus. It is the punishment associated with the breaking of the covenant (see Genesis 17:14). Such a person claimed to have peace with God while violating his laws. This judgment was a direct intervention of God.
20 Tout homme pur peut manger de la chair; mais celui qui, se trouvant en état d'impureté, mangera de la chair du sacrifice d'actions de grâces qui appartient à l'Eternel, celui-là sera retranché de son peuple.
