 This guy was a shill. He was there to debunk Jesus, I suspect. That's why it says that will be proof for them. But something that makes me think even more strongly that this guy is a shill is because of what follows. When he entered Capernaum, this is verse five. This is the next story in the gospel. When he entered Capernaum, a centurion approached him, said, Lord, my servant, literally my boy, my servant is lying at home paralyzed, suffering dreadfully. He said, I'll come and cure him.
