Jesus knew his time was coming to an end and after the confirmation moment of the transformation had pushed to teach all he could to his disciples.The chief priests confront Jesus in the temple and interrogate Him about His authority. They publicly ask Him a framing question hoping to entrap Him.

Jesus entered the temple courts, and, while he was teaching, the chief priests and the elders of the people came to him. “By what authority are you doing these things?” they asked. “And who gave you this authority?” Jesus replied, “I will also ask you one question. If you answer me, I will tell you by what authority I am doing these things. John’s baptism, where did it come from? Was it from heaven, or of human origin?” They discussed it among themselves and said, “If we say, ‘From heaven,’ he will ask, ‘Then why didn’t you believe him?’ But if we say, ‘Of human origin’, we are afraid of the people, for they all hold that John was a prophet.” So they answered Jesus, “We don’t know.” Then he said, “Neither will I tell you by what authority I am doing these things.
