Mark 11:27-32

They came again to Jerusalem. While Jesus was walking in the temple courts, the chief priests, the experts in the law, and the elders came up to him and said, “By what authority are you doing these things? Or who gave you this authority to do these things?” Jesus said to them, “I will ask you one question. Answer me and I will tell you by what authority I do these things: John’s baptism – was it from heaven or from people? Answer me.” They discussed with one another, saying, “If we say, ‘From heaven,’ he will say, ‘Then why did you not believe him?’ But if we say, ‘From people – ’” (they feared the crowd, for they all considered John to be truly a prophet).
