Hebrews 13:12-14
So Jesus also suffered outside the gate in order to sanctify the people through his own blood.
Therefore let us go to him outside the camp and bear the reproach he endured.
For here we have no lasting city, but we seek the city that is to come.
Exodus 33:7-11
7 Now Moses used to take a tent and pitch it outside the camp some distance away, calling it the “tent of meeting.” Anyone inquiring of the Lord would go to the tent of meeting outside the camp. 8 And whenever Moses went out to the tent, all the people rose and stood at the entrances to their tents, watching Moses until he entered the tent. 9 As Moses went into the tent, the pillar of cloud would come down and stay at the entrance, while the Lord spoke with Moses. 10 Whenever the people saw the pillar of cloud standing at the entrance to the tent, they all stood and worshiped, each at the entrance to their tent. 11 The Lord would speak to Moses face to face, as one speaks to a friend. Then Moses would return to the camp, but his young aide Joshua son of Nun did not leave the tent.
