And did eat up all the herbs in their land,.... As these creatures usually do, unless restrained, Exo 10:5. And devoured the fruit of their ground; which the hail left, Exo 10:15. . Psalms 105:36 psa 105:36 psa 105:36 psa 105:36He smote also all the firstborn in their land,.... Both of men and beasts; the firstborn of the king on the throne, and of the maidservant behind the mill, and of the captive in the dungeon; this was the last plague, and which prevailed upon the Egyptians to let Israel go, Exo 11:5. The chief of all their strength; or the first of their strength; the same in different words as before, their firstborn; see Gen 49:3.
