The chapter opens with the word the prophet Jeremiah spoke to Baruch son of Neriah, when he wrote these words in a book at Jeremiah's dictation, in the fourth year of Jehoiakim son of Josiah, king of Judah. This corresponds to what is told in chapter 36.
Baruch had said: woe is me! The Lord has added sorrow to my pain; I am weary with my groaning and find no rest. It is an honest complaint from someone who carried a hard task: writing messages of judgment, being persecuted for it and living in very difficult times.
The Lord answers him through Jeremiah. He tells him that what he has built he is breaking down, and what he has planted he is plucking up, that is, this whole land. And he asks whether Baruch seeks great things for himself. He tells him not to seek them, for he will bring disaster on all flesh. But he promises that in every place where he goes, I will give you your life as a prize of war, that is, he will escape with his life amid the disaster.
