John Gill Commentary Jeremiah 44:16

"As for the word that thou hast spoken unto us in the name of Jehovah, we will not hearken unto thee." — Jeremiah 44:16 (ASV)

[As for] the word that you have, spoken to us in the name of the Lord Which they did not believe that it came from the Lord, but was a device of the prophet's, and a lie, as in (Jeremiah 43:2) ; and if it did come from the Lord, their impudence was risen to such a pitch, that they were determined not to regard it: we will not hearken to you : to your words; neither to your exhortations, reproofs, or menaces, even though you come and speak in the name of the Lord. This, and what follows, is an unparalleled instance of the pride, obstinacy, enmity, and rebellion of the carnal mind against God.
