Matthew Poole and continuators on Jeremiah 14:4

4 Because the ground is chapt , for there was no rain in the earth, the plowmen were ashamed, they covered their heads .

The Heb. word signifieth more largely than chapt, broken, spoiled, turn'd into dust, as is usual in great droughts.

The word also which we translate Plowmen, doth not strictly signifie Plowmen, but Husbandmen, there having been no rain upon the Earth, it brought forth little or no grass for those that imployed themselves in breeding or feeding Cattel, and it was so hard, and so much wanted moisture, that they could not Plow nor Sow, but were like men ashamed and confounded, who knew not what to do.
