Chap. 7
verses 1-3
Moses' last difficulty (Exo 6:12, repeated in Exo 6:30) was removed by God with the words: “See, I have made thee a god to Pharaoh, and Aaron thy brother shall be thy prophet” (Exo 7:1). According to Exo 4:16, Moses was to be a god to Aaron; and in harmony with that, Aaron is here called the prophet of Moses, as being the person who would announce to Pharaoh the revelations of Moses. At the same time Moses was also made a god to Pharaoh; i.e., he was promised divine authority and power over Pharaoh, so that henceforth there was no more necessity for him to be afraid of the king of Egypt, but the latter, notwithstanding all resistance, would eventually bow before him. Moses was a god to Aaron as the revealer of the divine will, and to Pharaoh as the executor of that will. - In Exo 7:2-5 God repeats in a still more emphatic form His assurance, that notwithstanding the hardening of Pharaoh's heart, He would bring His people Israel out of Egypt. ושׁלּח (Exo 7:2) does not mean ut dimittat or mittat (Vulg. Ros.; “that he send,” Eng. ver.); but ו is vav consec. perf., “and so he will send.” On Exo 7:3 cf. Exo 4:21.
verses 4-7
Exo 7:4-7 את־ידי ונתתּי: “I will lay My hand on Egypt,” i.e., smite Egypt, “and bring out My armies, My people, the children of Israel.” צבאות (armies) is used of Israel, with reference to its leaving Egypt equipped (Exo 13:18) and organized as an army according to the tribes (cf. Exo 6:26 and Exo 12:51 with Num 1 and 2), to contend for the cause of the Lord, and fight the battles of Jehovah. In this respect the Israelites were called the hosts of Jehovah. The calling of Moses and Aaron was now concluded. Exo 7:6 and Exo 7:7 pave the way for the account of their performance of the duties consequent upon their call.
verses 8-13
The negotiations of Moses and Aaron as messengers of Jehovah with the king of Egypt, concerning the departure of Israel from his land, commenced with a sign, by which the messengers of God attested their divine mission in the presence of Pharaoh (Exo 7:8-13), and concluded with the announcement of the last blow that God would inflict upon the hardened king (Exo 11:1-10). The centre of these negotiations, or rather the main point of this lengthened section, which is closely connected
