Hebrews 13:11-13

For the bodies of those animals whose blood is brought into the sanctuary by the high priest as an offering for sin, are burned outside the camp. [Lev 16:27] Therefore Jesus also suffered and died outside the [city] gate so that He might sanctify and set apart for God as holy the people [who believe] through [the shedding of] His own blood. So, let us go out to Him outside the camp, bearing His contempt [the disgrace and shame that He had to suffer]. [Lev 16:27]
