Matthew Poole and continuators on Jeremiah 36:20

20 And they went in to the king, into the court, but they laid up the roll in the chamber of Elishama the scribe, and told all the words in the ears of the king .

They were obliged by their Office as Councellors to the King, to acquaint him with what they heard, which might be prejudicial to him, and his Nation, and indeed this was the very end, why God had commanded the enrolling of these Prophecies, that both the King, and Princes, and People might take notice of them, but they did not carry the book with them, but laid it up in the Secretaries Chamber.
