Adam Clarke's Bible Commentary Verse 7. The magicians did so] A little juggling or dexterity of hand might have been quite sufficient for the imitation of this miracle, because frogs in abundance had already been produced; and some of these kept in readiness might have been brought forward by the magicians, as proofs of their pretended power and equality in influence to Moses and Aaron.
Matthew Henry Commentary
Verses 1-15 - Pharaoh is plagued with frogs; their vast numbers made them sor 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 thes despicable creatures. God, when he pleases, can arm the smallest part of the creation against us. He thereby humbled Pharaoh. They shoul 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 wil 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 wa respite, he hardened his heart. Till the heart is renewed by the grac of God, the thoughts made by affliction do not abide; the conviction 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.
