18 Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now. 19 Now therefore command that all of your livestock and all that you have in the field be brought into shelter. Every man and animal that is found in the field, and isn’t brought home, the hail shall come down on them, and they shall die.”’” 20 Those who feared the word of Yahweh among the servants of Pharaoh made their servants and their livestock flee into the houses. 21 Whoever didn’t respect the word of Yahweh left his servants and his livestock in the field.

22 Yahweh said to Moses, “Stretch forth your hand toward the sky, that there may be hail in all the land of Egypt, on man, and on animal, and on every herb of the field, throughout the land of Egypt.” 23 Moses stretched forth his rod toward the heavens, and Yahweh sent thunder, hail, and lightning flashed down to the earth. Yahweh rained hail on the land of Egypt. 24 So there was very severe hail, and lightning mixed with the hail, such as had not been in all the land of Egypt since it became a nation. 25 The hail struck throughout all the land of Egypt all that was in the field, both man and animal; and the hail struck every herb of the field, and broke every tree of the field. 26 Only in the land of Goshen, where the children of Israel were, there was no hail. 27 Pharaoh sent, and called for Moses and Aaron, and said to them, “I have sinned this time. Yahweh is righteous, and I and my people are wicked. 28 Pray to Yahweh; for there has been enough of mighty thunderings 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 spread abroad my hands to Yahweh. The thunders shall cease, neither shall there be any more hail; that you may know that the earth is Yahweh’s. 30 But as for you and your servants, I know that you don’t yet fear Yahweh God.” 31 The flax and the barley were struck, for the barley was in the ear, and the flax was in bloom. 32 But the wheat and the spelt were not struck, for they had not grown up. 33 Moses went out of the city from Pharaoh, and spread abroad his hands to Yahweh; and the thunders and hail ceased, and the rain was not poured on the earth. 34 When Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants. 35 The heart of Pharaoh was hardened, and he didn’t let the children of Israel go, just as Yahweh 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.
