John Trapp on Jeremiah 13:7

Ver. 7. Then I went to Euphrates] See on ver. 4. Thoſe that are for an actual journey, alledge, that Jeremy might do this without danger in the dayes of Jehoiakim, who was the King of Babylons Vaſſal, and paid him tribute.

And behold the girdle was rotted, it was profitable for nothing] This ſhewed that the Jews ſhould in that Country lye rotting, as it were in baſeneſſe and ſervility and ſin together, many years: ſo that God might juſtly have left them there ſtill in miſery, as a man leaves his rotten girdle to become dung.
