I don't receive glory from men.

 There were three Jewish feasts which were feasts of obligation--Passover, Pentecost and Tabernacles. Every adult male Jew who lived within fifteen miles of Jerusalem was legally bound to attend them. If we take John 6:1-71 before John 5:1-47 we may think of this feast as Pentecost, because the events of John 6:1-71 happened when the Passover was near ( John 6:4). The Passover was in mid-April, and Pentecost was seven weeks later. John always shows us Jesus attending the great feasts, for Jesus did not disregard the obligations of Jewish worship. To him it was not a duty but a delight to worship with his own people.
