John 7:15-17

Young's Literal Translation

¹⁵ and the Jews were wondering, saying, `How hath this one known letters -- not having learned?'

¹⁶ Jesus answered them and said, `My teaching is not mine, but His who sent me;

¹⁷ if any one may will to do His will, he shall know concerning the teaching, whether it is of God, or -- I do speak from myself.
