Mark 11:28

And say unto him, by what authority dost thou do these things ?.... Enter into the temple, as if he was Lord of it; and correct in such a magisterial way every thing he thought an abuse in it; do the miracles he did, as healing the lame, and blind; and take upon him to instruct the people, a work he was now engaged in:

and who gave thee this authority to do these things ? See Gill on Matthew 21:23 .
