Luke 23:16

It ws a very common punishment among the Jews to scourge those who had committed crimes for which death would have been too severe. According to the laws of the Hebrews, (Deuteronomy xxv. 3.) the number of blows could not exceed thirty-nine. Pilate dares not condemn Jesus to death, because he believes him innocent; yet not to disoblige the people and magistrates, who demanded his death, he takes a middle way, which, as is usual in such cases, satisfies neither party. He neither saves the innocent Victim, nor satisfies justice. In lieu of one punishment, Jesus suffers two. He is at length both scourged and crucified. (Calmet)
