It is enough - There is no need of any farther plague; I submit to the authority of Jehovah and will rebel no more.

Mighty thunderings - כלת אלהים koloth Elohim, voices of God; - that is, superlatively loud thunder. So mountains of God (Psalm 36:6) means exceeding high mountains. So a prince of God (Genesis 23:6) means a mighty prince. See a description of thunder, Psalm 29:3-8 : "The Voice Of The Lord is upon the waters: the God of glory thundereth; the Lord is upon many waters. The voice of the Lord is powerful; the voice of the Lord is full of majesty. The voice of the Lord breaketh the cedars. The voice of the Lord divideth the flames of fire. The voice of the Lord shaketh the wilderness," etc. The production of rain by the electric spark is alluded to in a very beautiful manner, Jeremiah 10:13 : When he uttereth his voice, there is a multitude of waters in the heavens. See Clarke's note on Genesis 7:11, and Genesis 8:1 (note).

Entreat the Lord, for it is enough,.... Hail, thunder, and lightning enough; or pray that this may be enough, and thought sufficient, and that there may be no more; or "entreat the Lord, and much" (l); pray, and pray much, pray earnestly and without intermission until the plague ceases:

that there be no more mighty thunderings and hail; or "voices of God" (m); for thunder is the voice of God, and these thunderings or voices were very loud, the claps were very terrible to hear, and the hail was very grievous and heavy, and the whole was very amazing and frightful, and the more to Pharaoh, who perhaps had never heard the voice of thunder, or seen an hail storm before, even a common one, these being rare in the land of Egypt:

and I will let you go, and ye shall stay no longer; go the three days' journey into the wilderness, directly and immediately; he would not put it off, on any account, and much less refuse to let them go at all, as he had often done.

(l) "orate multam", Rivet. (m) "voces Dei", Montanus, Drusius.

Entreat the LORD (for it is enough) that there be no more mighty thunderings and hail; and I will let you go, and ye shall stay no longer.

mighty...: Heb. voices of God

9:22-35 Woful havoc this hail made: it killed both men and cattle; the corn above ground was destroyed, and that only preserved which as yet was not come up. The land of Goshen was preserved. God causes rain or hail on one city and not on another, either in mercy or in judgment. Pharaoh humbled himself to Moses. No man could have spoken better: he owns himself wrong; he owns that the Lord is righteous; and God must be justified when he speaks, though he speaks in thunder and lightning. Yet his heart was hardened all this while. Moses pleads with God: though he had reason to think Pharaoh would repent of his repentance, and he told him so, yet he promises to be his friend. Moses went out of the city, notwithstanding the hail and lightning which kept Pharaoh and his servants within doors. Peace with God makes men thunder-proof. Pharaoh was frightened by the tremendous judgment; but when that was over, his fair promises were forgotten. Those that are not bettered by judgments and mercies, commonly become worse.
