This chapter contains the title or inscription of the book; the call of the prophet to his office, and the encouragement he had to enter upon it. In the inscription the prophet is described by his name, by his descent, by the place of his birth, and the time of his prophesying, Jer 1:1, the appointment and ordination of him to his office, which was very early, and the signification of it to him, are in Jer 1:4, his excuse, on account of his childhood and weakness, Jer 1:6, the encouragement given him, notwithstanding this, from the mission and command he had from the Lord, and the promise of his presence with him, Jer 1:7, and not only is he encouraged by words, but also by signs; by the Lord's touching his mouth with his hand, as a symbol of putting his words into his mouth, and setting him over nations and kingdoms, to publish in a prophetic way their destruction, Jer 1:9, and by a vision of an almond tree, signifying the quick and hasty performance of the word of the Lord by him, Jer 1:11, and by another vision of a seething pot northwards, intimating the coming of the Chaldeans from the north against Jerusalem, and their taking it, and carrying the Jews captive because of their wickedness, which was a principal part of the message he was sent with, Jer 1:13 and the chapter is concluded with an exhortation to him to take heart, and be of good courage, and not be dismayed; since he was made a defenced city, an iron pillar, and brasen wall, against the whole land of Judea, its kings, princes, priests, and people; who, though they should fight against him, should not prevail, because God was with him, Jer 1:17.
