John Calvin on Jeremiah 14:4

The Prophet had said, that though the whole common people were sent to the waters, yet none would be found. He now adds the same firing respecting the husbandmen. Ashamed, he says, shall be the husbandmen, for the ground shall be turned into dust, and God will pound it small. When the heavens supply moisture, the earth retains thus its solid character; but in a great heat we see the earth dissolving into dust, as though it was pounded in a mortar.

So he says, On account of the chapt ground, because there is no rain, ashamed shall be the husbandmen, and they shall cover their heads; for sorrow shall not only seize on them, but also fin them with such shame as to make them to shun the light and the sight of men. These things were intended for the same purpose, even to make the Jews to know that they were not by chance deprived of water, but because God had cursed their land, so that it yielded them no water even for the common wants of nature. It follows —

Jeremiah 14:5-6

5. Yea, the hind also calved in the field, and forsook it, because there was no grass.

5. Quin etiam cerva in agro peperit et deseruit (nempe, foetum suum,) quia non fuit herba.

6. And the wild asses did stand in the high places, they snuffed up the wind like dragons; their eyes did fail, because there was no grass.

6. Et onagri steterunt super excelsa (diximus de hoc nomine, super labia, vel, eminentias, vel, rupes,) traxerunt (vel, hauserunt) ventum sicut serpentes; defecerunt oculi eorum, quia non fuit herba (utitur alio nomine, posuerat דשא prius, nunc ponit עשב sed eodem sensu.)
