Mark 15:20
And when they had mocked him, they took off the purple robe and put his own clothes on him. Then they led him out to crucify him — the purple robe is removed and the ordinary clothes restored — the mockery is finished and the execution is proceeding. The restoration of his own clothes communicates that he goes to his death not as a criminal in prison clothes but as himself, in his own garments that the soldiers will cast lots for (verse 24).
