Mark 11:31-33

Young's Literal Translation

³¹ And they were reasoning with themselves, saying, `If we may say, From heaven, he will say, Wherefore, then, did ye not believe him?

³² But if we may say, From men,' -- they were fearing the people, for all were holding John that he was indeed a prophet;

³³ and answering they say to Jesus, `We have not known;' and Jesus answering saith to them, `Neither do I tell you by what authority I do these things.'
