Matthew Poole and continuators on Jeremiah 9:7

7 Therefore thus saith the LORD of hosts; Behold, I will melt them, and try them: for how shall I do for the daughter of my people?

The same Metaphor used, chap. 6.29▪ try them by melting them, i. e. either I will try what lesser afflictions will do, before I do utterly destroy them, or rather, I will bring judgment upon them, the fire, and fury of the Chaldeans War, that shall clear away their dross from among them, and purge away those deceits, in which they trust, that the remnant may be purified. Dan. 11.35. as when the dross is separated from metals, the rest remains pure, see on Isa. 1.25.

q. d. There is no remedy I have tried all other means, and they have been in effectual, my people will take no warning, they are grown to such an height of impiety, that I can do no less, though they are my people, Hos. 6.4. or God doth expostulate with them, how can you expect, that I should treat you otherwise, that have so provoked me, and whose impieties have redounded so much to my dishonour.
