²⁷ The bull and the goat for the sin offerings, whose blood was brought into the Most Holy Place to make atonement, must be taken outside the camp;^(A) their hides, flesh and intestines are to be burned up. ²⁸ The man who burns them must wash his clothes and bathe himself with water; afterward he may come into the camp.^(B)
