v1-3: Mock worship, in form and word; no reality, faith, devotion, obedience. This was not the same as dead ritualism (Matt 12.7); but neither are true worship. The purple robe would be worn by royalty or nobility, see Luke 16.19.
v4-5: Pilate repeated his opinion of Christ's innocence. However, he still had Him scourged (whipped). He allowed his soldiers to mock Jesus, and he later had Him delivered to the Jews (v16). Pilate was inconsistent; pragmatic, unprincipled leadership. As in 18.38, and v8-9,13, he went back and forward, unable to decide what to do. In reality, Pilate was himself on trial before the King of Kings.
v6: Pilate correctly said that there was "no basis for a charge," or 'no fault' in Jesus; there was no wrong-doing, nothing worthy of blame.
Pilate spoke of a king, of truth, or power, but understood none of those things.
v7-8: The Jews made a truer statement than earlier, in 18.30. Their charge was essentially religious, not criminal. This made Pilate afraid. He could deal with criminals, carrying out the appropriate punishment, but 'religious' claims and disputes were not part of his jurisdiction nor his experience.
Pilate was afraid. 'Pilate's unease or fear in the presence of Jesus indicates that Pilate, in his attempt to exact his authority by ascribing to himself almost the divine prerogative which is actually true of Jesus, only discovers that he is confronted with one who is Himself at the course of all authority.' (Jesus and the Gospel in Africa, page 103, quoting Barnabas Linders, The Gospel of John.
v9: In returning to Jesus, Pilate received no answer. Jesus remained silent to many questions.
v10-11: Pilate attacked Jesus' silence, declaring that he had power over Him. But, he learned, that power was not his, but came from God. The guilty ones were those who delivered Jesus to him.
v12-16: Pilate wanted to set Jesus free, and said so. But the answer came back that such an action would be disloyalty to Caesar himself. Pilate wanted to end the whole affair, washing his hands of the matter. He therefore delivered Jesus to be crucified.
It was now the sixth hour of the morning (6.00 a.m.). Jesus was put on the cross three hours later (Mark 15.25). John uses Roman time, not Jewish time. It was hardly 12 hours since the meal (13.1), and Jesus probably hadn't slept during that period.
"We have no king but Caesar," announced the chief priests. See 1 Sam 8.6-7, where the people rejected God as their king, and sought a human king. The people were disloyal to God, and this statement powerfully confirmed it.
v17-18: Jesus was handed over to the soldiers, who would doubtless have continued the mistreatment of Jesus.
v19-22: Pilate had the title, the accusation against Jesus, written on the cross. This was a way of mocking the Jews rather than showing any respect towards Jesus.
The Jews would not accept Jesus as His word, "He claimed to be the Son of God," (v7) "anyone who claims to be a king" (v12).
v23-24: The soldiers were utterly callous, and at the same time totally ignorant of the significance of their actions. They wanted the few things belonging to the Saviour, yet had no interest in Him at all.
There is a danger in enjoying the things of Chris, or being involved in His things, but missing out on the greater blessing of knowing Him.
v25: The faithful few, who stood near the cross, identifying with their beloved Jesus.
v26-27: Joseph, Mary's husband, was now dead. There is no reference to him since Jesus was 12 years old (Luke 2.41-51). John now had to take responsibility for Mary. In the midst of His suffering, Jesus spoke words of compassion and unselfishness.
It seems that John may also have been related to Mary, perhaps through Zachariah or Elizabeth. That would be consistent with his links with the priests.
v28-30: We might think that Jesus cried out "I thirst," because of the excruciating pain of dehydration. John tells us that he cried out "I thirst" because the scripture had to be fulfilled. He deliberately quotes Ps 22.15, so that we might consider David's detailed and anguished propehcy a millenium earlier.
Pilate's words were over, the soldiers had finished gambling, Mary had a home. All attention in now totally upon Jesus Christ. His victorious words, "It is finished," salvation achieved without the help of a man.
v31-37: John remained to witness events.
The next day was a special Sabbath, additional to the normal weekly Sabbath. This Sabbath would begin, we understand, at 6.00 p.m. (western time) on the Thursday. The ordinary Sabbath would end at 6.00 p.m. (western time) on the Saturday. The women did not go to the tomb until the following morning (20.1).
It was the Jews' request that the bodies be removed before the Sabbath. When the criminals had not died, their legs were broken to hasten their deaths. The soldiers found that Jesus was already dead, and did not break His legs. A soldier pierced His side, and blood and water (or what appeared to be water) flowed out. This, we understand, is a clear indication of death.
John, knowing Jewish religious practice, explained the matter of the Sabbath. He also watched as the soldiers pierced Jesus' side. He saw too the significance of the events, as other prophesies were fulfilled.
v38-42: Joseph's fear, but see Mark 15.43; he went boldly into see Pilate. No more fear or doubt; now was a time for commitment and decision.
Num 19.11 indicates that Joseph and Nicodemus would be considered unclean (contrast 18.38), and therefore loose the respect of the religious leaders. Nicodemus was no longer "one of them" (7.50). Popular religion rejected Christ; but if we are loyal to Christ we must also reject popular religion.
John explained Jewish burial customs, and made reference to the Preparation Day and the special Sabbath. He was both knowledgeable about Jewish matters, and also concerned to make things clear for his readers.
At His coming into the world Jesus was wrapped in strips of cloth, and put in a borrowed place. At His death, He experienced the same. He had nothing in this world, yet He made it and owns it (1.10).
