The Jews therefore answered him, "What sign do you show us, seeing that you do these things?"
      (1.) Their demand of a sign: Then answered the Jews, that is the multitude of the people, with their leaders. Being Jews, they should rather have stood by him, and assisted him to vindicate the honour of their temple; but, instead of this, they objected against it. Note, Those who apply themselves in good earnest to the work of reformation must expect to meet with opposition. When they could object nothing against the thing itself, they questioned his authority to do it: "What sign showest thou unto us, to prove thyself authorized and commissioned to do these things?" It was indeed a good work to purge the temple; but what had he to do to undertake it, who was in no office there? They looked upon it as an act of jurisdiction, and that he must prove himself a prophet, yea, more than a prophet. But was not the thing itself sign enough? His ability to drive so many from their posts, without opposition, was a proof of his authority; he that was armed with such a divine power was surely armed with a divine commission. What ailed these buyers and sellers, that they fled, that they were driven back? Surely it was at the presence of the Lord (Psalms 114:5; Psalms 114:7), no less a presence.
