2. Mose 8:7

This miracle was also imitated by the Egyptian augurs with their secret arts, and frogs were brought upon the land by them. But if they were able to bring the plague, they could not take it away. The latter is not expressly stated, it is true; but it is evident from the fact that Pharaoh was obliged to send for Moses and Aaron to intercede with Jehovah to take them away. The king would never have applied to Moses and Aaron for help if his charmers could have charmed the plague away. Moreover the fact that Pharaoh entreated them to intercede with Jehovah to take away the frogs, and promised to let the people go, that they might sacrifice to Jehovah (Exo 8:8), was a sign that he regarded the God of Israel as the author of the plague. To strengthen the impression made upon the king by this plague with reference to the might of Jehovah, Moses said to him (Exo 8:9), "Glorify thyself over me, when I shall entreat for thee," i.e., take the glory upon thyself of determining the time when I shall remove the plague through my intercession. The expression is elliptical, and לעמר (saying) is to be supplied, as in Jdg 7:2. To give Jehovah the glory, Moses placed himself below Pharaoh, and left him to fix the time for the frogs to be removed through his intercession.

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).

8:7-8 The magicians were able to duplicate the plague in some sense, but Pharaoh did not ask them to rid the land of the frogs. Instead, he begged Moses to ask God to take them away. He already knew where the real power was.
