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.Villages - Literally, enclosures, or courtyards. 8-15. Pharaoh called, … Intreat the Lord, that he may take away the frogs from me—The frog, which was now used as an instrument of affliction, whether from reverence or abhorrence, was an object of national superstition with the Egyptians, the god Ptha being represented with a frog's head. But the vast numbers, together with their stench, made them an intolerable nuisance so that the king was so far humbled as to promise that, if Moses would intercede for their removal, he would consent to the departure of Israel, and in compliance with this appeal, they were withdrawn at the very hour named by the monarch himself. But many, while suffering the consequences of their sins, make promises of amendment and obedience which they afterwards forget; and so Pharaoh, when he saw there was a respite, was again hardened [Ex 8:15]. Doubtless they cast them into their rivers, or pits, &c., though that be not here mentioned. God would not instantly and wholly take them away, both to convince them of the truth of the miracle, and to make them more sensible of this judgment, and more fearful of bringing another upon themselves.

And they gathered them together upon heaps,.... Swept them up, and laid them in heaps out of the way:

and the land stank; with the stench of the dead frogs, which was another proof and evidence of the reality of the miracle; and that dead frogs will cause such an ill smell appears from the above account of what befell the inhabitants of Paeonia and Dardania, unless that should be the same with this, only the names of places and some circumstances altered; See Gill on Exodus 8:16.

And they gathered them together upon heaps: and the land stank.
