Charles Ellicott Commentary Jeremiah 36:32

"Then took Jeremiah another roll, and gave it to Baruch the scribe, the son of Neriah, who wrote therein from the mouth of Jeremiah all the words of the book which Jehoiakim king of Judah had burned in the fire; and there were added besides unto them many like words." — Jeremiah 36:32 (ASV)

And there were added besides unto them many like words. —The passage is interesting as showing, as it were, the genesis of the present volume of the prophet’s writings. The discourse delivered in the Temple court was, in modern phrase, revised and enlarged, dictated to Baruch as before, and in this shape has probably come down to us in Jeremiah 25.
