Mark - 11:29 Meaning
“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.”
King James Version (KJV)
Matthew Henry's Concise Commentary
11:27-33 Our Saviour shows how near akin his doctrine and baptism were to those of John; they had the same design and tendency, to bring in the gospel kingdom. These elders did not deserve to be taught; for it was plain that they contended not for truth, but victory: nor did he need to tell them; for the works he did, told them plainly he had authority from God; since no man could do the miracles which he did, unless God were with him.
“O LORD of hosts, God of Israel, that dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth: thou hast made heaven and earth.”
