28 Then they took Jesus from Caiaphas to Pilate's headquarters. It was early in the morning. They themselves did not enter the headquarters, so as to avoid ritual defilement and to be able to eat the Passover. 29 So Pilate went out to them and said, "What accusation do you bring against this man?" 30 They answered, "If this man were not a criminal, we would not have handed him over to you." 31 Pilate said to them, "Take him yourselves and judge him according to your law." The Jews replied, "We are not permitted to put anyone to death." 32 (This was to fulfill what Jesus had said when he indicated the kind of death he was to die.)

Commentary on John 18:28-32
(Read John 18:28-32)
It was unjust to put one to death who had done so much good, therefore the Jews were willing to save themselves from reproach. Many fear the scandal of an ill thing, more than the sin of it. Christ had said he should be delivered to the Gentiles, and they should put him to death; hereby that saying was fulfilled. He had said that he should be crucified, lifted up. If the Jews had judged him by their law, he had been stoned; crucifying never was used among the Jews. It is determined concerning us, though not discovered to us, what death we shall die: this should free us from disquiet about that matter. Lord, what, when, and how, thou hast appointed.
