Albert Barnes Commentary Jeremiah 23:10

"For the land is full of adulterers; for because of swearing the land mourneth; the pastures of the wilderness are dried up. And their course is evil, and their might is not right;" — Jeremiah 23:10 (ASV)

Because of swearing - Rather, because of the curse denounced against sin (Jeremiah 11:3). The mourning probably refers to the drought (Jeremiah 12:4).

The pleasant places - “Pastures.”

Their course - Their mode of life.

Their force is not right - “Their heroism,” that on which they pride themselves as mighty men, “is not right,” is wrong (see Jeremiah 8:6 note).
