Why in John 18:38 did Jesus not reply when he was asked about truth?

John 18:38 says that Pilate asked Jesus “what is truth?” There are two possible answers that can be given for this verse. The first is that the question is rhetorical, which is a question that is asked in such a way that a answer is not necessary. I think it is safe to say that we all know what truth is. Aristotle probably provided the best definition which is, ‘saying it like it is.” When you read the verse in context, it even reads like a rhetorical question.

The second possible answer is that Jesus was again fulfilling prophecy; this one from Isaiah 53:7 which says that “He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is silent, so he opened not his mouth.”

Both these responses are acceptable, but which one is the correct answer we do not know, but this does not deny Jesus’ divinity.
