John Trapp on Jeremiah 36:16

Ver. 16. They were afraid both one and other] Expaveſcunt & ſeſe mutuo respiciunt, they were afraid and looked one upon another, being much diſtracted at this new and unexpected occurrence; neither wiſt they at firſt what to do, being affected after a ſort, and ſmitten with the weightineſſe of the buſineſſe.

We will ſurely tell the King] They durſt do no otherwiſe: for if theſe things ſhould have come to the Kings ear, and they not firſt tell him, they might come into the danger of his diſpleaſure.
