John Trapp on Jeremiah 23:10

Ver. 10. For the land is full of adulterers] It is even become a great brothelhouſe, as ſometimes Cyprus was: and as Rome is now ſaid to be; —tota est jam Roma lupanar.

For becauſe of ſwearing (or, curſing) the land mourneth] Swearers and curſers then are publike enemies, traytours to the State. The Jews obſerve that Beerſhaba ſignifies the well of oath, and Beerſaba the well of plenty. Sure we are, that for oaths the land mourneth: of which there is ſuch ſtore, as if men, by an eaſie miſtake of the point, uſed to draw and drop them, as it were, out of the well of plenty.

And the pleaſant places] Or, paſtures or habitations: which being dryed up, ſeem to mourn: and yet the inhabitants are without all ſenſe of ſorrow.

And their courſe is evil] Naught all over, as we ſay.

And their force is not right] Not rightly employed: they are not valiant for the truth, but violent for wrong doing.
