Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
In chapter 1 the prophet is established in his office, to which he had been appointed by Jehovah, even before his birth, that he should carry His word unto the nations. But Jeremiah's fears are immediately manifested. The Lord encourages him by the assurance of His presence. He puts His words into his mouth, and appoints him as prophet over the nations to root out and to plant. Two visions are shewn him, which contain the summary of the prophetic charge communicated to him, and announce that Jerusalem shall soon be stricken by the kingdoms of the north. Under these circumstances Jeremiah is set before a rebellious people, who will strive against him. Nevertheless he must declare everything; and as the Lord had before encouraged the prophet, He now adds to the encouragement, in order to enforce it, a threat in case of disobedience; namely, that, if through fear he drew back from his commission, the Lord would become a greater cause of fear, and would break him to pieces before those of whom he was afraid. But if he fulfilled his appointed task, Jehovah would be with him. Jer 1:6-8; Jer 1:17-18, shew the great fearfulness of the prophet's spirit, which needed to be thus strengthened by Jehovah.
