“And Jesus answered and said unto them, I also will ask you one thing, which if ye tell me, I in like wise will tell you by what authority I do these things.”
King James Version (KJV)
21:24 I will ask you one thing - Who have asked me many: The baptism, that is, the whole ministry of John, was it from heaven or from men? - By what authority did he act and teach? Did man or God give him that authority? Was it not God? But if so, the consequence was clear. For John testified that Jesus was the Christ.
Mt 21:24 I also will ask you one thing. A malicious question is often best answered by a question which will expose the questioners.
