John 7:14, 26, 28

But when it was now the midst of the feast Jesus went up into the temple, and began to teach.

Look, He is speaking publicly, and they are saying nothing to Him. The rulers do not really know that this is the Christ, do they?

Then Jesus cried out in the temple, teaching and saying, “You both know Me and know where I am from; and I have not come of Myself, but He who sent Me is true, whom you do not know.
