Mark 11:33

29Jesus said to them, “I will ask you one question. Answer me, and I will tell you by what authority I do these things.

30The baptism of John—was it from heaven, or from men? Answer me.”

31They reasoned with themselves, saying, “If we should say, ‘From heaven;’ he will say, ‘Why then did you not believe him?’

32If we should say, ‘From men’”—they feared the people, for all held John to really be a prophet.

33They answered Jesus, “We don’t know.” Jesus said to them, “Neither will I tell you by what authority I do these things.”
