The same melancholy theme is the subject of this chapter that was of those foregoing - the approaching ruin of Judah and Jerusalem for their sins. This Jeremiah had often foretold; here he has particularly full orders to foretel it again. I. He must set their sins in order before them, as he had often done, especially their idolatry (Jer 19:4, Jer 19:5). II. He must describe the particular judgments which were now coming apace upon them for these sins (Jer 19:6-9). III. He must do this in the valley of Tophet, with great solemnity, and for some particular reasons (Jer 19:2, Jer 19:3). IV. He must summon a company of the elders together to be witnesses of this (Jer 19:1). V. He must confirm this, and endeavour to affect his hearers with it, by a sign, which was the breaking of an earthen bottle, signifying that they should be dashed to pieces like a potter's vessel (Jer 19:10-13). VI. When he had done this in the valley of Tophet he ratified it in the court of the temple (Jer 19:14, Jer 19:15). Thus were all likely means tried to awaken this stupid senseless people to repentance, that their ruin might be prevented; but all in vain.
