This chapter is evidently connected with the subject treated of in the thirty-sixth. Baruch, who had written the prophecies of Jeremiah, and read them publicly in the temple, and afterwards to many of the princes, is in great affliction because of the awful judgments with which the land of Judah was about to be visited; and also on account of the imminent danger to which his own life was exposed, in publishing such unwelcome tidings, Jer 45:1-3. To remove Baruch's fear with respect to this latter circumstance, the prophet assures him that though the total destruction of Judea was determined because of the great wickedness of the inhabitants, yet his life should be preserved amidst the general desolation, Jer 45:4, Jer 45:5.
