Matthew 21:25-27

Young's Literal Translation

²⁵ the baptism of John, whence was it? -- from heaven, or from men?' And they were reasoning with themselves, saying, `If we should say, From heaven; he will say to us, Wherefore, then, did ye not believe him?

²⁶ and if we should say, From men, we fear the multitude, for all hold John as a prophet.'

²⁷ And answering Jesus they said, `We have not known.' He said to them -- he also -- `Neither do I tell you by what authority I do these things.
