Luke 23:4

I find no fault in this man - According to John 18:36, John 18:38, Pilate did not say this till after our Lord had declared to him that his kingdom was not of this world; and probably not till after he had found, on examining witnesses, (Luke 23:14), that all their evidence amounted to no proof, of his having set up himself for a temporal king. See Bishop Pearce.

I find no fault - I see no evidence that he is guilty of what you charge him with. This was after Pilate had taken Jesus into the judgment-hall by himself and examined him "privately," and had been satisfied in regard to the nature of his kingdom. See John 18:33-38. He was "then" satisfied that though he claimed to be "a king," yet his kingdom was not of this world, and that "his" claims did not interfere with those of Caesar.

23:4 Then said Pilate - After having heard his defence - I find no fault in this man - I do not find that he either asserts or attempts any thing seditious or injurious to Cesar.
