Exodus 7:20

He lifted up the rod. — “He” is, undoubtedly, Aaron. (See Exodus 7:19.)

In the sight of Pharaoh, and in the sight of his servants. — If the occasion was one of a Nile festival, Pharaoh would have “gone out to the water” (Exodus 7:15) accompanied by all the great officers of the Court, by a large body of the priests, and vast numbers of the people. If it was a mere occasion of bodily ablution, he would have had with him a pretty numerous train of attendants. In either case considerable publicity was given to the miracle, which was certainly not “done in a corner.”
