"'What shall I do, then, with the one you call the king of the Jews?' Pilate asked them. 'Crucify him!' they shouted." NIV translation
The politician continues to play to the wishes of the mob as he asks them what to do with Jesus. Their answer was to have Him crucified and we often forget that this was not a punishment that was handed down to your average person who committed a crime. This punishment was reserved for slaves and the vilest of offenders and was designed to maximize suffering and humiliation. It makes us ask the question of why the crowd would call for that punishment. It comes down to the fact that the leaders of the religious system wanted to disgrace Jesus and, by doing so, to cause His followers to abandon what they considered to be a cult.
"'Why? What crime has he committed?' asked Pilate. But they shouted all the louder, 'Crucify him!'" NIV translation
In this verse, we are reminded of the fact that Pilate knew that Jesus had not committed a crime but he also was willing to do whatever it took to keep his position and authority.
This also serves to remind us of the way things will be in the last days. A political leader will emerge that will stir up the masses and oppose God much like what was happening here. Even so, we are once again reminded of the fact that this was all in God's plan and He is in control.
"Wanting to satisfy the crowd, Pilate released Barabbas to them. He had Jesus flogged, and handed him over to be crucified." NIV translation
Pilate went above and beyond the desires of the crowd as he delivered Jesus up first to be flogged. This was a process where the prisoner was whipped using a special whip that had pieces of bone embedded in the ends of the strips of leather. These pieces of bone would rip through the flesh and cause maximum damage and suffering. The Jews limited flogging to 40 lashes but would actually limit it to 39 in case there was a miscount. The Romans had no such restriction and, in fact, many people did not survive the flogging.
