John Gill Commentary Jeremiah 20:16

"And let that man be as the cities which Jehovah overthrew, and repented not: and let him hear a cry in the morning, and shouting at noontime;" — Jeremiah 20:16 (ASV)

And let that man be as the cities which the Lord overthrew ,
&c.] In his fury, as the Targum and Septuagint add. Meaning the cities of Sodom and Gomorrah, who were utterly destroyed, and were never recovered: and repented not ;
whose sentence God never repented of, nor revoked: this was very severe and uncharitable, to wish for so sore a destruction upon an innocent person; and let him hear the cry in the morning, and the shouting at noontide ;
as soon as he is up in the morning, the first thing that salutes his ears, let it be the noise of an enemy invading the city he dwells in; and by noon let him hear the shouting of him, having broke in, and gotten the victory, seizing the plunder.
