Your own nation and the chief priests delivered You to me; what have You done?” 36 Jesus answered, “My kingdom is not of this world. If My kingdom were of this world, then My servants would be fighting so that I would not be handed over to the Jews; but as it is, My kingdom is not of this realm.” 37 Therefore Pilate said to Him, “So You are a king?” Jesus answered, “You say correctly that I am a king. For this I have been born, and for this I have come into the world, to testify to the truth. Everyone who is of the truth hears My voice.” 38 Pilate said to Him, “What is truth.” John 18:33-38 NASB

Then He made the following statement, “Everyone who is of the truth hears My voice.” Of course Pilate made the following sarcastic response, “What is truth?”
