Why was a sin offering from which any blood was brought into the tent of meeting forbidden to be eaten?
If some of the blood had been brought into the sanctuary itself, it would be a violation for the priest to eat any of it. If that were to happen, the sacrificial animal was to be wholly consumed by fire.
23 Mais on ne mangera aucune victime dans la tente d'assignation, pour faire l'expiation dans le sanctuaire: elle sera brûlée au feu.
