Here, I. God encourages Moses to go to Pharaoh, and at last silences all his discouragements. 1. He clothes him with great power and authority (Exo 7:1): I have made thee a god to Pharaoh; that is, my representative in this affair, as magistrates are called gods, because they are God's viceregents. He was authorized to speak and act in God's name and stead, and, under the divine direction, was endued with a divine power to do that which is above the ordinary power of nature, and invested with a divine authority to demand obedience from a sovereign prince and punish disobedience. Moses was a god, but he was only a made god, not essentially one by nature; he was no god but by commission. He was a god, but he was a god only to Pharaoh; the living and true God is a God to all the world. It is an instance of God's condescension, and an evidence that his thoughts towards us are thoughts of peace, that when he treats with men he treats by men, whose terror shall not make us afraid. 2. He again nominates him an assistant, his brother Aaron, who was not a man of uncircumcised lips, but a notable spokesman: "He shall be thy prophet," that is, "he shall speak from thee to Pharaoh, as prophets do from God to the children of men. Thou shalt, as a god, inflict and remove the plagues, and Aaron, as a prophet, shall denounce them, and threaten Pharaoh with them." 3. He tells him the worst of it, that Pharaoh would not hearken to him, and yet the work should be done at last, Israel should be delivered and God therein would be glorified, Exo 7:4, Exo 7:5. The Egyptians, who would not know the Lord, should be made to know him. Note, It is, and ought to be, satisfaction enough to God's messengers that, whatever contradiction and opposition may be given them, thus far they shall gain their point, that God will be glorified in the success of their embassy, and all his chosen Israel will be saved, and then they have no reason to say that they have laboured in vain. See here, (1.) How God glorifies himself; he makes people know that he is Jehovah. Israel is made to know it by the performance of his promises to them (Exo 6:3), and the Egyptians are made to know it by the pouring out of his wrath upon them. Thus God's name is exalted both in those that are saved and in those that perish. (2.) What method he takes to do this: he humbles the proud, and exalts the poor, Luk 1:51, Luk 1:52. If God stretch out his hand to sinners in vain, he will at last stretch out his hand upon them; and who can bear the weight of it?

II.Moses and Aaron apply themselves to their work without further objection: They did as the Lord commanded them, Exo 7:6. Their obedience, all things considered, was well worthy to be celebrated, as it is by the Psalmist (Psa 105:28), They rebelled not against his word, namely, Moses and Aaron, whom he mentions, v. 26. Thus Jonah, though at first he was very averse, at length went to Nineveh. Notice is taken of the age of Moses and Aaron when they undertook this glorious service. Aaron the elder (and yet the inferior in office) was eighty-three, Moses was eighty; both of them men of great gravity and experience, whose age was venerable, and whose years might teach wisdom, v. 7. Joseph, who was to be only a servant to Pharaoh, was preferred at thirty years old; but Moses, who was to be a god to Pharaoh, was not so dignified until he was eighty years old. It was fit that he should long wait for such an honour, and be long in preparing for such a service.

I have made thee a god - At thy word every plague shall come, and at thy command each shall be removed. Thus Moses must have appeared as a god to Pharaoh.

Shall be thy prophet - Shall receive the word from thy mouth, and communicate it to the Egyptian king, Exo 7:2.

And the Lord said unto Moses,.... In answer to his objection, taken from his own meanness, and the majesty of Pharaoh, and from his want of readiness and freedom of expression:

see; take notice of, observe what I am about to say:

I have made thee a god to Pharaoh; not a god by nature, but made so; he was so by commission and office, clothed with power and authority from God to act under him in all things he should direct; not for ever, as angels are gods, but for a time; not in an ordinary way, as magistrates are gods, but in an extraordinary manner; and not to any other but to Pharaoh, being an ambassador of God to him, and as in his room and stead to, rule over him, though so great a monarch; to command him what he should do, and control him when he did wrong, and punish him for his disobedience, and inflict such plagues upon him, and do such miracles before him, as no mere man of himself, and none but God can do; and even exercise the power of life and death, as in the slaying of the firstborn, that Pharaoh should stand in as much fear of him, as if he was a deity, and apply to him to remove the plagues upon him, as if he was one:

and Aaron thy brother shall be thy prophet; to declare the will of God revealed to him by Moses from the Lord; so that this seems to be more than to be the mouth and spokesman of Moses and interpreter and explainer of his words, or to be acting the part of an orator for him; for Moses in this affair being God's viceregent, and furnished with a knowledge of the mind and will of God respecting it, as well as with power to work miracles, and inflict plagues, was made a god to both Pharaoh and Aaron; see Exo 4:6 to Pharaoh in the sense before explained, and to Aaron, he being his prophet, to whom he communicated the secrets of God, and his will and pleasure, in order to make the same known to Pharaoh. Thus highly honoured was Moses to be a god to a sovereign prince, and to have Aaron to be his prophet.
