Mark 11:28-30

King James Version

²⁸ And say unto him, By what authority doest thou these things? and who gave thee this authority to do these things?

²⁹ And Jesus answered and said unto them, I will also ask of you one question, and answer me, and I will tell you by what authority I do these things.

³⁰ The baptism of John, was it from heaven, or of men? answer me.
