Jeremiah, often called the "weeping prophet" because of his sorrow over the persistent message of God's judgment, prophesied to the nation of Judah from the reign of King Josiah in 627 b.c. until sometime after the destruction of Jerusalem in 586. He dictated his prophecies to a scribe named Baruch (36:4, 32). Jeremiah's task as a prophet was to declare the coming judgment of God. However, throughout the book we also see God's concern for repentance and righteousness in individuals as well as nations. This dual focus is seen in God's instructions to Jeremiah: he was "to pluck up and to break down" but also "to build and to plant" (1:10). Jeremiah sees a future day when God will write his law on human hearts, and "they shall all know me," and "I will remember their sin no more" (31:33-34).
