Jeremiah 28:12

It hence appears that Jeremiah had regard only to the common benefit of the people, and that he wisely kept silence for a time, that he might not throw pearls before swine, and thus expose in a manner the holy name of God to the insolence of the ungodly. He therefore waited until he might again go forth with new messages, and thus secure more credit to himself. For had he contended longer with Hananiah, contentions would have been kindled on every side, there would have been no hearing in a tumult, and the Jews would have wholly disregarded anything he might have then spoken. But as he had withdrawn from the crowd, and was afterwards sent by God, the Jews could not have so presumptuously despised him or his doctrine. This, then, was the reason why he was for a short time silent.

If he feared and trembled in the midst of these commotions, God in due time confirmed him by giving him new commands: The word of Jehovah, he says, came to Jeremiah, after Hananiah broke the band from his neck. By these words he intimates, that the ungodly, however insolently they may rise up against God, ever depart with shame and reproach. For Hananiah had not only opposed Jeremiah by his words and tongue, but had also broken the cords or bands from his neck. This, then, the Prophet now repeats, in order that he might shew, as it were by his finger, that Hananiah by his audacity gained nothing, except that he rendered his vanity more notorious.
