Mark 15:16-20

Mark 15:16 (KJB)
And the soldiers led him away into the hall, called Praetorium; and they call together the whole band.

Then the crowd, Jesus, and the soldiers were still outside of the judgment seat where he just sat. The praetorium would have been the former palace of Herod in the western part of the city. This is where Pilate resided during the days of the feasts. Jesus would definitely have been in a weakened state from the loss of blood and the pain from the scourging. There were only a few hundred soldiers in Israel at the time which was a cohort or 1/10 of a legion which would be 600 soldiers. So quite a number must have been assembled because of the ferocity of the crowd. They took Jesus from the place where He was scourged to the common hall.

Mark 15:17 (KJB)
And they clothed him with purple, and platted a crown of thorns, and put it about his head,

In the palace Jesus was again stripped of all His clothing and they placed upon Him a purple or scarlet robe. (Mat 27:28 KJV) And they stripped him, and put on him a scarlet robe. The color “purple” had varied from a scarlet red to a deep purple and that depended upon the variety of shell fish from which the dye was derived. Now when we realize the amount of openings in the skin from the scourging, the robe would adhere to the cuts and start to help heal them like a scab. When the robe would be removed, then it would be like He was scourged all over again because the cloth would rip out of the wounds and cause the pain. The color purple was the color of royalty and the robe of red they placed on Jesus was nothing more than an act of ridicule. We could look at this scarlet robe as the robe of sins which He bore for the Elect of God.

Then the next element of humiliation was they placed a crown of thorns on His head. These would have been long thorns woven together in a crown of some type of grass or hedge. The thorns would have been placed on His head very hard to cause the thorns to go into His scalp and cause pain and bleeding. Just as the Judaizers became the thorn in the flesh to Paul, Jesus also felt the thorns of the Judaizers, the ones who rejected and hated Him and His followers. (2 Cor 12:7 KJV) And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.

Mark 15:18 (KJB)
And began to salute him, Hail, King of the Jews!

As the soldiers were mocking Jesus by dressing Him in royal colors, they were continually hailing Him as King of the Jews. The Roman soldiers probably saw the soldiers of Herod do it so they now joined in and mocked Jesus. Pilate did not join them in this heinous act.

Mark 15:19 (KJB)
And they smote him on the head with a reed, and did spit upon him, and bowing their knees worshipped him.

The soldiers then continued their humiliating treatment of Jesus as they began to spit on Him. Then they continued to torture Jesus by hitting Him on the head with the reed which caused the large thorns to go deeper into the scalp. The Greek imperfect tense behind the word “smote” tells us that they kept striking Him repeatedly. Thorns were also the curse on the ground that came from man’s sin. (Gen 3:18 KJV) Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field; The crown of thorns was the very symbol of the curse of mankind.

Mark 15:20 (KJB)
And when they had mocked him, they took off the purple from him, and put his own clothes on him, and led him out to crucify him.

Once the time of mocking was finished, they then ripped the robe off of Him which would have once again opened the wounds from the scourging and made it feel like a second scourging. Then they placed His own garments upon Him and started the walk to where He would be crucified. By this time now Jesus would have been forced to carry His own cross and would soon buckle under from the weight of it.
