John Trapp on Jeremiah 18:23

Ver. 23. Yet Lord, thou knoweſt all their counſel] Though I know it not, yet thou art privy to it, and canſt prevent it; for wiſdom and might are thine, Dan. 2.20.

To ſlay me] All malice is bloody.

Forgive not their iniquity] He knew their ſin to be unpardonable: and therefore prayeth for vengeance upon them unavoydable. This was fulfilled upon the Jews by the Babylonians in reſpect of Jeremy, and by the Romans in reſpect of Chriſt.

Neither blot out their ſin from thy ſight] A heavy curſe. Woe to ſuch as whoſe debts ſtand uncroſſed in Gods book. Their ſins may ſleep a long time, like a ſleeping debt, not called for of many years: as Sauls ſin in ſlaying the Gibeonites was not puniſhed till forty years after: as Joabs killing of Abner ſlept all Davids dayes. Mens conſciences alſo may ſleep (in ſuch a caſe) for a ſeaſon: but their damnation ſleepeth not: nor can their condition be ſafe till God have wiped out their ſins for his own ſake: till he have croſſed out the black lines of our iniquities with the red lines of his Sons blood, and taken out of his coffers ſo much as may fully ſatisfie, &c.
