Mark 15:2

And Pilate asked him, art thou the king of the Jews ?.... Which either he had heard before that it was said by him, and his followers; or was what the Jews now suggested to him as his crime, which they desired sentence of death might pass upon him:

and he answering, said unto him, thou sayest it ; which is all one as if he had said, I am; See Gill on Matthew 26:25 ; for so he was in a sense, in which he explained himself to Pilate's satisfaction, John 18:36 ; See Gill on Matthew 27:11 .
