Jeremiah 36:13

Then Micaiah declared all the words that he had heard
The sum and substance of them; for it cannot be thought that he should retain in his memory every word that he had heard; though, as it is very probable he was much struck and affected with what he had heard, he might remember and declare a great deal of it: when Baruch read the book in the ears of the people;
and this he also declared, no doubt, that what he had heard, and then related, were read by Baruch out of a book; as is clear from the princes sending for Baruch, and ordering him to bring the roll along with him, as in ( Jeremiah 36:14 ) .
