Matthew Henry on Jeremiah 14:10-16

The Lord calls the Jews "this people," not "his people." They had forsaken his service, therefore he would punish them according to their sins. He forbade Jeremiah to plead for them. The false prophets were the most criminal. The Lord pronounces condemnation on them; but as the people loved to have it so, they were not to escape judgments. False teachers encourage men to expect peace and salvation, without repentance, faith, conversion, and holiness of life. But those who believe a lie must not plead if for an excuse. They shall feel what they say they will not fear.
