John 7:16

Jesus responded by explaining that His knowledge had come from the One who had sent Him, namely, God the Father (cf. John 5:19-30). It had not come from Himself. He meant that His was not knowledge that He had dreamed up or arrived at through independent study. Jewish rabbis normally cited other rabbis as the sources of their information. Jesus avoided giving the impression that He was an inventive upstart, but He also implied that His teaching was not simply the continuation of rabbinic tradition. His teaching did not come from the rabbis or from self-study but directly from God.

"It is characteristic of many of the outstanding men of the Bible that they are convinced that they must do what they are doing, and say what they are saying, because they have received a divine commission." [Note: Tasker, p. 104.]
