Hebrews 13:12-14

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] For here we have no lasting city, but we are seeking the city which is to come.
