Luke 20:1-8
On one of the days while He was teaching the people in the temple and preaching the gospel, the chief priests and the scribes with the elders confronted Him, and they spoke, saying to Him, “Tell us by what authority You are doing these things, or who is the one who gave You this authority?” Jesus answered and said to them, “I will also ask you a question, and you tell Me: Was the baptism of John from heaven or from men?” They reasoned among themselves, saying, “If we say, ‘From heaven,’ He will say, ‘Why did you not believe him?’But if we say, ‘From men,’ all the people will stone us to death, for they are convinced that John was a prophet.” So they answered that they did not know where it came from. And Jesus said to them, “Nor will I tell you by what authority I do these things.”
Mark 11:27-33
They came again to Jerusalem. And as He was walking in the temple, the chief priests and the scribes and the elders came to Him, and began saying to Him, “By what authority are You doing these things, or who gave You this authority to do these things?” And Jesus said to them, “I will ask you one question, and you answer Me, and then I will tell you by what authority I do these things. Was the baptism of John from heaven, or from men? Answer Me.” They began reasoning among themselves, saying, “If we say, ‘From heaven,’ He will say, ‘Then why did you not believe him?’ But shall we say, ‘From men’?”—they were afraid of the people, for everyone considered John to have been a real prophet. Answering Jesus, they said, “We do not know.” And Jesus said to them, “Nor will I tell you by what authority I do these things.”
Matthew 21:23-32
When He entered the temple, the chief priests and the elders of the people came to Him while He was teaching, and said, “By what authority are You doing these things, and who gave You this authority?” Jesus said to them, “I will also ask you one thing, which if you tell Me, I will also tell you by what authority I do these things. The baptism of John was from what source, from heaven or from men?” And they began reasoning among themselves, saying, “If we say, ‘From heaven,’ He will say to us, ‘Then why did you not believe him?’ But if we say, ‘From men,’ we fear the people; for they all regard John as a prophet.” And answering Jesus, they said, “We do not know.” He also said to them, “Neither will I tell you by what authority I do these things.
“But what do you think? A man had two sons, and he came to the first and said, ‘Son, go work today in the vineyard.’ And he answered, ‘I will not’; but afterward he regretted it and went. The man came to the second and said the same thing; and he answered, ‘I will, sir’; but he did not go. Which of the two did the will of his father?”
They said, “The first.” Jesus said to them, “Truly I say to you that the tax collectors and prostitutes will get into the kingdom of God before you. For John came to you in the way of righteousness and you did not believe him; but the tax collectors and prostitutes did believe him; and you, seeing this, did not even feel remorse afterward so as to believe him.
