Charles Ellicott Commentary Jeremiah 2:1

"And the word of Jehovah came to me, saying," — Jeremiah 2:1 (ASV)

The first chapter had given the narrative of the call which had impressed itself indelibly on the prophet’s mind. The next five run on as one continuous whole. Considering that the original record of his prophetic work during Josiah’s reign had been destroyed by Jehoiakim (Jeremiah 36:23) and was later rewritten from memory, it is probable that we have a kind of précis of what was then destroyed, with some additions (Jeremiah 36:32) and possibly some omissions. In Jeremiah 3:6, the name of Josiah is definitely mentioned.
