John Gill Bible Commentary

Now it came to pass, when Jeremiah had made an end of speaking,.... For they let him alone till he had done, either out of reverence of him as a priest and prophet; or they were awed by a secret influence on their minds that they might not disturb him: all that the Lord had commanded him to speak unto all the people; he did as he was ordered, kept back nothing, not fearing the resentment of the people, but fearing God: that the priests, and the prophets, and all the people, took him; the priests and the prophets were the leading men in this action; they stirred up the people against him, and through their instigation he was seized and laid hold on: saying, thou shall surely die; signifying that they would bring a charge against him, which they were able to support, and which by the law would be death; unless they meant in the manner of zealots to put him to death themselves, without judge or jury; and which they would have put in execution, had not the princes of the land, or the great sanhedrim, heard of it; and therefore to prevent it came to the temple, as is afterwards related.
