Leviticus 4:12

Without the camp - This was intended figuratively to express the sinfulness of this sin, and the availableness of the atonement. The sacrifice, as having the sin of the priest transferred from himself to it by his confession and imposition of hands, was become unclean and abominable, and was carried, as it were, out of the Lord' s sight; from the tabernacle and congregation it must be carried without the camp, and thus its own offensiveness was removed, and the sin of the person in whose behalf it was offered. The apostle (Hebrews 13:11-13) applies this in the most pointed manner to Christ: "For the bodies of those beasts whose blood is brought into the sanctuary by the high priest for sin, are burned without the camp. Wherefore Jesus also, that he might sanctify the people with his own blood, suffered without the gate. Let us go forth therefore unto him without the camp, bearing his reproach."
