Mark 11:27-33
27Again they came to Jerusalem. As he was walking in the temple, the chief priests, the scribes, and the elders came to him
28and said, By what authority are you doing these things? Who gave you this authority to do them?
29Jesus said to them, I will ask you one question; answer me, and I will tell you by what authority I do these things.
30Did the baptism of John come from heaven, or was it of human origin? Answer me.
31They argued with one another, If we say, From heaven, he will say, Why then did you not believe him?
32But shall we say, Of human origin? they were afraid of the crowd, for all regarded John as truly a prophet.
33So they answered Jesus, We do not know. And Jesus said to them, Neither will I tell you by what authority I am doing these things.
