Verse 5. - Over the streams... rivers... ponds. See the comment on Exodus 7:19.

8:1-15 Pharaoh is plagued with frogs; their vast numbers made them sore plagues to the Egyptians. God could have plagued Egypt with lions, or bears, or wolves, or with birds of prey, but he chose to do it by these despicable creatures. God, when he pleases, can arm the smallest parts of the creation against us. He thereby humbled Pharaoh. They should neither eat, nor drink, nor sleep in quiet; but wherever they were, they should be troubled by the frogs. God's curse upon a man will pursue him wherever he goes, and lie heavy upon him whatever he does. Pharaoh gave way under this plague. He promises that he will let the people go. Those who bid defiance to God and prayer, first or last, will be made to see their need of both. But when Pharaoh saw there was respite, he hardened his heart. Till the heart is renewed by the grace of God, the thoughts made by affliction do not abide; the convictions wear off, and the promises that were given are forgotten. Till the state of the air is changed, what thaws in the sun will freeze again in the shade.And the Lord spake unto Moses,.... By a secret impulse upon his mind, for he was now in the presence of Pharaoh, who had refused to let Israel go:

say unto Aaron, stretch forth thy hand with thy rod; for Aaron carried the rod, and he was the minister of Moses, who was appointed a god to him; and be was to speak and to do whatever he ordered him from the Lord:

over the streams, over the rivers and over the ponds; the seven streams of the river of Nile, and over the canals cut out of it, and over all places where there was a collection of water for any use for man or beast:

and cause frogs to come up upon the land of Egypt; out of the streams, rivers, and ponds, immediately.
