Adam Clarke on John 7:16

My doctrine is not mine - Our blessed Lord, in the character of Messiah, might as well say, My doctrine is not mine, as an ambassador might say, I speak not my own words, but his who sent me: and he speaks these words to draw the attention of the Jews from the teaching of man to the teaching of God; and to show them that he was the promised Messiah, the very person on whom, according to the prophet, (Isa 11:2), the Spirit of Jehovah - the Spirit of wisdom, counsel, understanding, might, and knowledge, should rest.
