And Moses and Aaron did as the Lord commanded them,.... After this they never showed any reluctance, or made any objection to any message they were sent with, or any work they were ordered to do, but went about it at once, and performed it with all readiness and cheerfulness:

so did they; which is not a superfluous and redundant expression, but very emphatic, showing with what care and diligence they did every thing, and how exactly they conformed in all things to the divine will.

And Moses and Aaron did as the LORD commanded them, so did they.

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.
