Matthew 21:26 YLT

²⁴  And Jesus answering said to them, 'I will ask you -- I also -- one word, which if ye may tell me, I also will tell you by what authority I do these things;

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.

²⁸  'And what think ye? A man had two children, and having come to the first, he said, Child, go, to-day be working in my vineyard.'
