Exodus 29:14
But burn the bull's flesh and its hide and its intestines outside the camp. It is a sin offering. The sin offering's flesh, hide, and intestines are burned outside the camp — not on the altar. What was not consumed on the altar is consumed outside the sacred precinct. Hebrews 13:11–12 cites this explicitly: the animals whose blood is brought into the Most Holy Place by the high priest as a sin offering are burned outside the camp. And so Jesus also suffered outside the city gate. The burning outside the camp that disposes of the sin offering is the pattern fulfilled at the crucifixion: Jesus died outside Jerusalem, outside the sacred precinct, as the sin offering whose blood was brought into the Most Holy Place.
