Matthew 27:26
Then he released for them Barabbas, and having scourged Jesus, delivered him to be crucified. The release of Barabbas and the scourging and delivery of Jesus: the substitution that the Passover custom produced is the enacted parable of the atonement. The scourging — the brutal Roman flogging with the leather whip embedded with bone and metal — precedes the crucifixion as the standard Roman execution procedure.
