John Trapp on Jeremiah 15:18

Ver. 18. Why is my pain perpetual, &c.] Here the Prophet over-freely expoſtulateth with God, as leſſe faithful, or leſſe mindful at leaſt, of the promiſed preſervation: This was in a fit of diffidence and diſcontent, as the beſt have their outburſts, and the greateſt lamps have needed ſnuffers. The Mileſians, ſaith the Philoſopher, are not fools: yet they do the things that fools uſe to do: So the Saints do oft as wicked ones, but not in the ſame manner and degree.
