John Gill Commentary Luke 23:3

"And Pilate asked him, saying, Art thou the King of the Jews? And he answered him and said, Thou sayest." — Luke 23:3 (ASV)

And Pilate asked him, saying
Observing that it was said, he had given himself out to be a king; for as for what regarded religion, he took no notice of it; he put this question to him,

are you the King of the Jews ?
that their prophecies speak of, and they have expected;

and he answered him and said, you say it ;
that is, you say well; it is as you say, I am the King of the Jews; (See Gill on Matthew 27:11) though he did not leave this without explaining what sort of a king he was, and what kind of a kingdom he had; see (John 18:36John 18:37) which made Pilate perfectly easy, and desirous to release him, as appears by what follows.
