Charles Ellicott Commentary Jeremiah 36:11

"And when Micaiah the son of Gemariah, the son of Shaphan, had heard out of the book all the words of Jehovah," — Jeremiah 36:11 (ASV)

When Michaiah the son of Gemariah ...— Gemariah himself was, as we find in the next verse, not one of the listeners, but took his place with the other princes, in the “scribe’s chamber,” probably used as a council room, in the king’s palace. It seems obvious from Michaiah’s relation to him that his purpose in reporting Baruch’s discourse was not unfriendly. Probably, it was part of a preconcerted plan, arranged between the prophet and his friends, that he should report it and so give an opening to bring Baruch into the presence of the king and his counselors, as they sat in what we may call their council chamber.
