18 Behold, about this time tomorrow I will cause very heavy hail to fall, such as never has been in Egypt from the day it was founded until now. 19 Now therefore send, get your livestock and all that you have in the field into safe shelter, for every man and beast that is in the field and is not brought home will die when the hail falls on them."'" 20 Then whoever feared the word of the Lord among the servants of Pharaoh hurried his slaves and his livestock into the houses, 21 but whoever did not pay attention to the word of the Lord left his slaves and his livestock in the field.
22 Then the Lord said to Moses, "Stretch out your hand toward heaven, so that there may be hail in all the land of Egypt, on man and beast and every plant of the field, in the land of Egypt." 23 Then Moses stretched out his staff toward heaven, and the Lord sent thunder and hail, and fire ran down to the earth. And the Lord rained hail upon the land of Egypt. 24 There was hail and fire flashing continually in the midst of the hail, very heavy hail, such as had never been in all the land of Egypt since it became a nation. 25 The hail struck down everything that was in the field in all the land of Egypt, both man and beast. And the hail struck down every plant of the field and broke every tree of the field. 26 Only in the land of Goshen, where the people of Israel were, was there no hail. 27 Then Pharaoh sent and called Moses and Aaron and said to them, "This time I have sinned; the Lord is in the right, and I and my people are in the wrong. 28 Plead with the Lord, for there has been enough of God's thunder and hail. I will let you go, and you shall stay no longer." 29 Moses said to him, "As soon as I have gone out of the city, I will stretch out my hands to the Lord. The thunder will cease, and there will be no more hail, so that you may know that the earth is the Lord's. 30 But as for you and your servants, I know that you do not yet fear the Lord God." 31 (The flax and the barley were struck down, for the barley was in the ear and the flax was in bud. 32 But the wheat and the emmer[1] were not struck down, for they are late in coming up.) 33 So Moses went out of the city from Pharaoh and stretched out his hands to the Lord, and the thunder and the hail ceased, and the rain no longer poured upon the earth. 34 But when Pharaoh saw that the rain and the hail and the thunder had ceased, he sinned yet again and hardened his heart, he and his servants. 35 So the heart of Pharaoh was hardened, and he did not let the people of Israel go, just as the Lord had spoken through Moses.

Commentary on Exodus 9:13-21
(Read Exodus 9:13-21)
Moses is here ordered to deliver a dreadful message to Pharaoh. Providence ordered it, that Moses should have a man of such a fierce and stubborn spirit as this Pharaoh to deal with; and every thing made it a most signal instance of the power of God has to humble and bring down the proudest of his enemies. When God's justice threatens ruin, his mercy at the same time shows a way of escape from it. God not only distinguished between Egyptians and Israelites, but between some Egyptians and others. If Pharaoh will not yield, and so prevent the judgment itself, yet those that will take warning, may take shelter. Some believed the things which were spoken, and they feared, and housed their servants and cattle, and it was their wisdom. Even among the servants of Pharaoh, some trembled at God's word; and shall not the sons of Israel dread it? But others believed not, and left their cattle in the field. Obstinate unbelief is deaf to the fairest warnings, and the wisest counsels, which leaves the blood of those that perish upon their own heads.
Commentary on Exodus 9:22-35
(Read Exodus 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.
