27 They came again to Jerusalem, and as he was walking in the temple, the chief priests, and the scribes, and the elders came to him, 28 and they began saying to him, “By what authority do you do these things? Or who gave you this authority to do these things?” 29 Jesus said to them, “I will ask you one question. 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 They reasoned with themselves, saying, “If we should say, ‘From heaven;’ he will say, ‘Why then did you not believe him?’ 32 If we should say, ‘From men’”—they feared the people, for all held John to really be a prophet. 33 They answered Jesus, “We don’t know.”
Jesus said to them, “Neither do I tell you by what authority I do these things.”

(Read Mark 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.
