Exodus 8:10

The king appointed the following day, probably because he hardly thought it possible for so great a work to be performed at once. Moses promised that it should be so: "According to thy word (sc., let it be), that thou mayest know that there is not (a God) like Jehovah our God." He then went out and cried, i.e., called aloud and earnestly, to Jehovah concerning the matter (דּבר על) of the frogs, which he had set, i.e., prepared, for Pharaoh (שׂוּם as in Gen 45:7). In consequence of his intercession God took the plague away. The frogs died off (מן מוּת, to die away out of, from), out of the houses, and palaces, and fields, and were gathered together by bushels (חמרים from חמר, the omer, the largest measure used by the Hebrews), so that the land stank with the odour of their putrefaction. Though Jehovah had thus manifested Himself as the Almighty God and Lord of the creation, Pharaoh did not keep his promise; but when he saw that there was breathing-time (רוחה, ἀνάψυξις, relief from an overpowering pressure), literally, as soon as he "got air," he hardened his heart, so that he did not hearken to Moses and Aaron (והכבּד inf. abs. as in Gen 41:43).

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).

8:10 you will know that there is no one like the Lord our God: Once more the issue is highlighted (see 7:17). These events were not primarily about rescue, but about the nature of reality. Who was rescuing these people—one of the gods, or the one true God, the Lord?
