2. Mose 7:9

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.

In this chapter, I. The dispute between God and Moses finishes, and Moses applies himself to the execution of his commission, in obedience to God's command (Exo 7:1-7). II. The dispute between Moses and Pharaoh begins, and a famous trial of skill it was. Moses, in God's name, demands Israel's release; Pharaoh denies it. The contest is between the power of the great God and the power of a proud prince; and it will be found, in the issue, that when God judgeth he will overcome. 1. Moses confirms the demand he had made to Pharaoh, by a miracle, turning his rod into a serpent; but Pharaoh hardens his heart against this conviction (Exo 7:8-13). 2. He chastises his disobedience by a plague, the first of the ten, turning the waters into blood; but Pharaoh hardens his heart against this correction, Exo 7:14, etc.).

7:9 Serpent (Hebrew tannin) is a different word than the word translated “snake” in 4:3. Tannin often refers to a sea monster. Egypt is often portrayed as an ultimately impotent sea monster (Isa 30:7; Ezek 29:3). The image of a cobra’s head was on the pharaoh’s headdress.
