Matthew 21:23-27

After this Jesus went into the temple courts and taught the people. The leading priests and Jewish elders approached him and interrupted him and asked, “By what power do you do these things, and who granted you the authority to teach here?” Jesus answered them, “I too have a question to ask you. If you can answer this question, then I will tell you by what power I do these things. Where did John’s authority to baptize come from? From heaven or from people?” They stepped away and debated among themselves, saying, “How should we answer this? If we say from heaven, he will say to us, ‘Then why didn’t you respond to John and believe what he said?’ But if we deny that God gave John his authority, we’ll be mobbed by the people, for they’re convinced that John was God’s prophet.” So they finally answered, “We don’t know.” “Then neither will I tell you from where my power comes to do these things!” he replied.
