Verse 2. - Thou shalt speak. The Septuagint and the Vulgate have, "Thou shalt speak to him," which undoubtedly gives the true sense. Moses was to speak to Aaron, Aaron to Pharaoh. (See Exodus 4:15, 16.)

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.Thou shalt speak all that I command thee,.... That is, to Aaron his prophet, whatever the Lord made known to him in a private manner as his will to be done:

and Aaron thy brother shall speak unto Pharaoh; whatsoever should be told him by Moses, as from the Lord:

that he send the children of Israel out of his land; this was the principal thing to be insisted upon; and all that was said or done to him was to bring about this end, the dismission of the children of Israel out of Egypt.
