Questioning of his authority
Shortly after entering the city of Jerusalem, Jesus goes up to the Temple. There the Pharisees and Sadducees try to trip him up, asking him about his authority. “By what authority are you doing these things?And who gave you this authority?” Jesus said to them in reply, “I shall ask you one question, and if you answer it for me, then I shall tell you by what authority I do these things. Where was John’s baptism from? Was it of heavenly or of human origin?” They discussed this among themselves and said, “If we say ‘Of heavenly origin,’ he will say to us, ‘Then why did you not believe him?’ But if we say, ‘Of human origin,’ we fear the crowd, for they all regard John as a prophet.” So they said to Jesus in reply, “We do not know.” He himself said to them, “Neither shall I tell you by what authority I do these things.
Then a group of the younger students from the academies, who had been rehearsed for this purpose, came forward and by their spokesman addressed Jesus: "Master, we know you are a righteous teacher, and we know that you proclaim the ways of truth, and that you serve only God, for you fear no man, and that you are no respecter of persons. We are only students, and we would know the truth about a matter which troubles us; our difficulty is this: Is it lawful for us to give tribute to Caesar? Shall we give or shall we not give?" Jesus, perceiving their hypocrisy and craftiness, said to them: "Why do you thus come to tempt me? Show me the tribute money, and I will answer you." And when they handed him a denarius, he looked at it and said, "Whose image and superscription does this coin bear?" And when they answered him, "Caesar's," Jesus said, "Render to Caesar the things that are Caesar's and render to God the things that are God's."
When he had thus answered these young scribes and their Herodian accomplices, they withdrew from his presence, and the people, even the Sadducees, enjoyed their discomfiture. Even the youths who had endeavored to entrap him marveled greatly at the unexpected sagacity of the Master's answer.
