See the notes at Matthew 27:32-37.
What I have written ... - This declaration implied that he would make no change. He was impatient, and weary of their solicitations. He had yielded to them contrary to the convictions of his own conscience, and he now declared his purpose to yield no further.
16 Then delivered he him therefore unto them to be crucified. And they took Jesus, and led him away.
17 And he bearing his cross went forth into a place called the place of a skull, which is called in the Hebrew Golgotha:
18 Where they crucified him, and two other with him, on either side one, and Jesus in the midst.
19 And Pilate wrote a title, and put it on the cross. And the writing was, JESUS OF NAZARETH THE KING OF THE JEWS.
20 This title then read many of the Jews: for the place where Jesus was crucified was nigh to the city: and it was written in Hebrew, and Greek, and Latin.
21 Then said the chief priests of the Jews to Pilate, Write not, The King of the Jews; but that he said, I am King of the Jews.
22 Pilate answered, What I have written I have written.
