God made Him who knew no sin to be sin on our behalf, so that in Him we might become the righteousness of God.
Hebrews 13:11–13
Although the high priest brings the blood of animals into the Holy Place as a sacrifice for sin, the bodies are burned outside the camp. / And so Jesus also suffered outside the city gate, to sanctify the people by His own blood. / Therefore let us go to Him outside the camp, bearing the disgrace He bore.
