Hebrews 13:13

(13) The suffering “without the gate” was a symbol of His rejection by the Jews. All who would be His must share the reproach which came upon Him, who was cast out by His people and crucified (Hebrews 11:26): they also must go forth “without the camp,” forsaking the company of His foes. Each one must for himself make choice either of the synagogue or of the church of Christ; between the two there can be no fellowship.
