Exodus 8:28

The plague of Frogs, or the second plague, also proceeded from the Nile, and had its natural origin in the putridity of the slimy Nile water, whereby the marsh waters especially became filled with thousands of frogs. צפרדּע is the small Nile frog, the Dofda of the Egyptians, called rana Mosaica or Nilotica by Seetzen, which appears in large numbers as soon as the waters recede. These frogs (הצּפרדּע in Exo 8:6, used collectively) became a penal miracle from the fact that they came out of the water in unparalleled numbers, in consequence of the stretching out of Aaron's staff over the waters of the Nile, as had been foretold to the king, and that they not only penetrated into the houses and inner rooms ("bed-chamber"), and crept into the domestic utensils, the beds (מטּה), the ovens, and the kneading-troughs (not the "dough" as Luther renders it), but even got upon the men themselves.

Three more of the plagues of Egypt are related in this chapter, I. That of the frogs, which is, 1. Threatened (Exo 8:1-4). 2. Inflicted (Exo 8:5, Exo 8:6). 3. Mimicked by the magicians (Exo 8:7). 4. Removed, at the humble request of Pharaoh (Exo 8:8-14), who yet hardens his heart, and, notwithstanding his promise while the plague was upon him (Exo 8:8), refuses to let Israel go (Exo 8:15). II. The plague of lice (Exo 8:16, Exo 8:17), by which, 1. The magicians were baffled (Exo 8:18, Exo 8:19), and yet, 2. Pharaoh was hardened (Exo 8:19). III. That of flies. 1. Pharaoh is warned of it before (Exo 8:20, Exo 8:21), and told that the land of Goshen should be exempt from this plague (Exo 8:22, Exo 8:23). 2. The plague is brought (Exo 8:24). 3. Pharaoh treats with Moses about the release of Israel, and humbles himself (Exo 8:25-29). 4. The plague is thereupon removed (Exo 8:31), and Pharaoh's heart hardened (Exo 8:32).
