go to Jerusalem, "not openly, but as it were in secret" (, NKJV translation) () "But when the middle feast day came, Jesus went up into the temple, and taught" (, Wycliffe Bible). H. W. Watkins supposes that the main party travelling from Galilee to Jerusalem would have taken the route to the east of the River Jordan, and that Jesus took the alternative route through Samaria, as he had done when he travelled back from Jerusalem to Galilee in chapter 4 and the Jamieson-Fausset-Brown Bible Commentary agrees that He may have travelled "perhaps by some other route". When Jesus began to teach in the Temple, he was perceived as being uneducated and yet learned (), not having received rabbinical, priestly or Sadduceean training. Jesus was known not to have learned through contemporary routes of Jewish learning such as the House of Hillel or the House of Shammai, and it is likely that both the content and the style of His teaching were seen as distinct from the teaching of the "Jews" of these schools, to whom the evangelist refers. "His teaching on this occasion was expository", based on the Hebrew Bible: Albert Barnes writes that "Jesus exhibited in his discourses such a profound acquaintance with the Old Testament as to excite [the] amazement and admiration" of other learned scholars, but He explains that His teaching is not His own, but "but His who sent Me" (). Jesus does not disown His teaching, but He does not claim to be its originator or its authority: "The 'my' refers to the teaching itself, the 'mine' to the ultimate authority on which it rests. I am not a self-taught Man, as though out of the depths of my own independent human consciousness I span it ... 'He who sent me' gave [it] to me. I have been in intimate communion with HIM. All that I say is Divine thought." The evangelist has already referred to four witnesses to the validity of Jesus' testimony (), and now adds that anyone who wants to do God's will know the authority of His teaching (). Learned discussion on Laws In a discussion which demonstrates this point to the learned Jews, Jesus then refers to the Mosaic law, and to the law and tradition of the patriarchs. The law of circumcision prescribed by Moses () originated with God's covenant with Abraham and required every male child
