Mark 11:31 ASV

²⁹  And Jesus said unto them, I will 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 from men? answer me.

³¹  And they reasoned with themselves, saying, If we shall say, From heaven; He will say, Why then did ye not believe him?

³²  But should we say, From men--they feared the people: for all verily held John to be a prophet.

³³  And they answered Jesus and say, We know not. And Jesus saith unto them, Neither tell I you by what authority I do these things.
