Multiple times in the Bible Jesus declares that He is the Truth, or that He is on the side of Truth.
John 14:6 NIV
Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.
“You are a king, then!” said Pilate. Jesus answered, “You say that I am a king. In fact, the reason I was born and came into the world is to testify to the truth. Everyone on the side of truth listens to me.”
What is Jesus referring to with this word, Truth? Pilate then asks Jesus this same question. But I don't think that Pilate was actually looking for an answer, this is more of a sarcastic rhetorical question to in my opinion.
“What is truth?” retorted Pilate. With this he went out again to the Jews gathered there and said, “I find no basis for a charge against him.
Can you answer that for me?
