In Egypt the cattle are sent to pasture in the open country from January to April, when the grass is abundant. They are kept in stalls for the rest of the year.

Send - now, and gather thy cattle - So in the midst of judgment, God remembered mercy. The miracle should be wrought that they might know he was the Lord; but all the lives both of men and beasts might have been saved, had Pharaoh and his servants taken the warning so mercifully given them. While some regarded not the word of the Lord, others feared it, and their cattle and their servants were saved, See Exodus 9:20, Exodus 9:21.

Send therefore now, and gather thy cattle, and all that thou hast in the field,.... The servants that were at work there: this is said to denote both the certainty of the plague, and the terribleness of it, that all, both men and beast, would perish by it, if care was not taken to get them home; and also to show the wonderful clemency and mercy of God to such rebellious, hardened, and undeserving creatures, as Pharaoh and his people were; in the midst of wrath and judgment God remembers mercy:

for upon every man and beast which shall be found in the field, and shall not be brought home; and there sheltered in houses, barns, and stables:

the hail shall come down upon them, and they shall die; the hailstones that would fall would be so large and so heavy as to kill both men and beasts, like those which fell from heaven upon the Canaanites in the days of Joshua, which killed more than the sword did, Joshua 10:11.

The good advice to be given by Moses to the king, to secure the men and cattle that were in the field, i.e., to put them under shelter, which was followed by the God-fearing Egyptians (Exodus 9:21), was a sign of divine mercy, which would still rescue the hardened man and save him from destruction. Even in Pharaoh's case the possibility still existed of submission to the will of God; the hardening was not yet complete. But as he paid no heed to the word of the Lord, the predicted judgment was fulfilled (Exodus 9:22-26). "Jehovah gave voices" (קלת); called "voices of God" in Exodus 9:28. This term is applied to the thunder (cf. Exodus 19:16; Exodus 20:18; Psalm 29:3-9), as being the mightiest manifestation of the omnipotence of God, which speaks therein to men (Revelation 10:3-4), and warns them of the terrors of judgment. These terrors were heightened by masses of fire, which came down from the sky along with the hail that smote man and beast in the field, destroyed the vegetables, and shattered the trees. "And fire ran along upon the ground;" תּהלך is a Kal, though it sounds like Hithpael, and signifies grassari, as in Psalm 73:9.

Send therefore now, and {e} gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.

(e) Here we see though God's wrath is kindled yet there is a certain mercy shown even to his enemies.

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.
