71 Then the Lord said to Moses, "See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. 2 You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. 3 But I will harden Pharaoh's heart, and though I multiply my signs and wonders in Egypt, 4 he will not listen to you. Then I will lay my hand on Egypt and with mighty acts of judgment I will bring out my divisions, my people the Israelites. 5 And the Egyptians will know that I am the Lord when I stretch out my hand against Egypt and bring the Israelites out of it." 6 Moses and Aaron did just as the Lord commanded them. 7 Moses was eighty years old and Aaron eighty-three when they spoke to Pharaoh.

Commentary on Exodus 7:1-7

(Read Exodus 7:1-7)

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, and the Egyptians by the pouring out of his wrath upon them. Moses, as the ambassador of Jehovah, speaking in his name, laid commands upon Pharaoh, denounced threatenings against him, and called for judgments upon him. Pharaoh, proud and great as he was, could not resist. Moses stood not in awe of Pharaoh, but made him tremble. This seems to be meant in the words, Thou shalt be a god unto Pharaoh. At length Moses is delivered from his fears. He makes no more objections, but, being strengthened in faith, goes about his work with courage, and proceeds in it with perseverance.
