Matthew Poole and continuators on Exodus 29:14

14 But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin-offering .

To wit, for the high-priest, as is plain from the whole context and therefore ought to be burnt, by that law, Lev. 4. There was indeed a law, that that sin-offering, whose blood was not carried into the Tabernacle, which was the case here, should not be burnt, but eaten, Lev. 6. 30. and 10. 18. But that concerned the people, not the priests, who did not eat, but burn, their own sin-offerings, Leviticus 4. 3, 12.
