12 And he slaughtereth the burnt-offering, and the sons of Aaron have presented unto him the blood, and he sprinkleth it on the altar round about; 13 and the burnt-offering they have presented unto him, by its pieces, and the head, and he maketh perfume on the altar; 14 and he washeth the inwards and the legs, and maketh perfume for the burnt-offering on the altar.
