John Gill Commentary Jeremiah 19:12

"Thus will I do unto this place, saith Jehovah, and to the inhabitants thereof, even making this city as Topheth:" — Jeremiah 19:12 (ASV)

Thus will I do unto this place, says the Lord, and to the inhabitants of it. To the city of Jerusalem and its inhabitants, as was done to the earthen bottle, and as before threatened: and [even] , or also, make this city as Tophet ; as full of slaughtered men and women as that has been of the blood of innocent children; and as filthy, abominable, and execrable a place as that; and to lose its name, as that is foretold it should, (Jeremiah 19:6); and as Jerusalem did, after the desolation of it by Hadrian, as Jerom observes; for what was built there afterwards was called Aelia by the emperor, after his own name.
