The authority of Jesus is questioned while he is teaching in the Temple in Jerusalem, as reported in all three synoptic gospels: Matthew 21:23–27, Mark 11:27–33 and Luke 20:1–8. … 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”.
In all three synoptic gospels, this episode takes place shortly after the cleansing of the Temple reported after Jesus’ triumphal entry into the city.The word “authority” (Greek: ἐξουσίᾳ, exousia means “authority”. The word derives from the verb exesti) is frequently used in relation to Jesus in the New Testament.
A similar episode is described in the Gospel of John at John 2:13–18) as part of the Cleansing of the Temple narrative. In John’s account, after expelling the merchants and the money changers from the Temple, Jesus is confronted.
