John 18:20 - Matthew Poole's English Annotations on the Holy Bible

I spake openly to the world; to all sorts of men, my enemies as well as my friends. I ever taught in the synagogue, and in the temple, whither the Jews always resort; the Jews for instruction do use to resort to the temple, which was in Jerusalem, and whither three times in the year all the males were wont to come from all parts of the country: and in the public assemblies of the Jews, and in the places where they use to meet. And in secret have I said nothing; I have said nothing in secret contrary to the doctrine which I have publicly taught; though I have preached in other places, yet it hath been the same thing which I have said in public.
