Jesus answered him, I have frankly (so Meyer, Lange; not "openly," but boldly, with freedom of speech) spoken £ to the world. Without reserving any of the essentials of my teaching, always I taught in £ synagogue, and in the temple, whither all the Jews resort and come together; and in secret spake I nothing, which they were not bidden to proclaim upon the housetops.
Christ here repudiates esoteric teaching distinct from his abundant public ministry. It is true he explained his parables to his disciples, and he had within the last few hours poured forth the depth of his feelings upon them; still, he had said the same things virtually in the synagogues, on the hillside, in the temple, in the hearing of Greek as well as Jew.
Much of that which he had just said in the upper chamber, hundreds and thousands had already heard. This great utterance accounts for the fact that St. Paul had received, long before the Fourth Gospel was written, truth allied to the teaching of the upper chamber.
