(22) Upon every herb of the field.--The damage that hail can do to crops is well known, and has given rise among ourselves to a special form of insurance. Such a storm as that here described would necessarily have destroyed all vegetation that was more than a few inches high, and must have greatly injured shrubs and fruit-trees. (See Exodus 9:25; Exodus 9:31.)

Verse 22. - Stretch forth thine hand toward heaven. The action was appropriate, as the plague was to come from the heaven. Similarly, in the first and second plagues, Aaron's hand had been stretched out upon the waters (Exodus 7:19, 20; Exodus 8:6); and in the third upon "the dust of the ground" (Exodus 8:17). And upon every herb of the field - i.e., upon all forms of vegetable life. (Compare Genesis 1:30; Genesis 9:3.)

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.And the Lord said unto Moses,.... When the morrow was come, the fifth day of the month Abib:

stretch forth thine hand toward heaven; with his rod in it, as appears from the next verse, to show that the following plague would come from the heaven, that is, the air, and from God, who dwells in the heaven of heavens:

that there may be hail in all the land of Egypt; not only in that spot, and near it, where Moses stood, and from that part of the heaven towards which he stretched forth his hand, but from the whole heaven all over the land of Egypt; which shows it to be an unusual and extraordinary hail, for a hail storm seldom reaches far, a mile it may be, or some such space; but never was such an one heard of as to reach through a whole country, and so large an one as Egypt:

upon man and upon beast; such as belonged to those who would take no warning, nor attend to the word of the Lord to fetch home their servants and cattle:

and upon every herb of the field throughout the land of Egypt; it should fall so thick, that scarce an herb would escape it.
