31. He spake, and there came a swarm of flies, 1 and lice 2 in all their borders. 32. He gave them hail for rain, and flaming fire upon their land. 33. And he smote their vines and their fig trees; and destroyed the trees throughout their borders. 34. He spake, and the grasshopper came, and the caterpillar 3 without number, 35. And they devoured all the herbage in their land, and consumed the fruit of their ground. 36. And he smote all the first-born in their country, even the beginning of all their strength. 437. And he brought them forth with silver and gold: nor was there a feeble person among his tribes. 38. Egypt rejoiced at their departure: for their terror had fallen upon them.
31. He spake, and there came a swarm of flies. By the word spake the Psalmist intimates that the flies and lice came not forth by chance. The command, we know, was uttered by the mouth of Moses; for although God could have given the command himself, he interposed Moses as his herald. God, however, gave no less efficacy to his word, when he commanded it to be uttered by a man, than if he himself had thundered from heaven. When the minister executes his commission faithfully, by speaking only what God puts into his mouth, the inward power of the Holy Spirit is joined with his outward voice. Here again it is to be observed, that the Egyptians were afflicted with the plague of the flies and lice, that God, with the greater ignominy, might subdue their rebellion and obstinacy. When it is said, that he gave them hail for rain, it denotes a hail of such appalling violence, that it could not be attributed to natural causes. It is probable that Egypt is not so subject to this annoyance as other countries, and it is very seldom visited even with rain, being watered with the Nile. This made it appear to the Egyptians the more wonderful that their country was stricken with hail. To render this calamity the more dreadful, God also mingled with it fire. The hail, then, was accompanied with a tempestuous whirlwind, that the Egyptians who had hardened themselves against the other miracles, inspired with terror, might know that they had to deal with God.
34. He spake, and the grasshopper came. This calamity, which was brought upon the fields, could not be attributed to Fortune; for the grasshoppers made their appearance suddenly and in countless multitudes, so that they covered all the land of Egypt. The miracle was very evident from the word spoken, by which it was introduced. Its being announced as to happen, removed all doubt of its being the work of the Most High. Accordingly, it is expressly said, that grasshoppers and caterpillars rushed in at the commandment of God, as if soldiers should run to battle at the sound of the trumpet. Whenever these insects molest us and destroy the fruits of the earth, they are assuredly the scourges of God, but it is here intended to point out an extraordinary work of his hand. In fine, the prophet recites the last miracle, which was wrought by the angel on the night previous to the departure of the people, when he slew all the first-born throughout Egypt. I only take a hasty and passing glance at this history, as I have, in like manner, done of the other facts preceding, because they have been more copiously treated elsewhere, and at this time it is sufficient for us to know the design of the sacred writer. He, however, amplifies this display of the Divine power by a repetition, declaring that the first-born and the flower of their strength were destroyed. Some translate, but unhappily, The beginning of their sorrow. As man's strength shows itself in generation, the Hebrews term the first-begotten the beginning of strength, as we have explained on Genesis 49:3, --
"Reuben, thou art my first-born, my might,
and the beginning of my strength."
37. And he brought them forth with silver and gold. 5 The prophet, on the other hand, celebrates the grace of God which preserved the chosen people untouched and safe from all these plagues. If both parties had been indiscriminately afflicted with them, the hand of God would not have been so signally manifest. But now when the Israelites, amidst so many calamities, experienced an entire exemption from harm, this difference exhibits to us, as in a picture, God's fatherly care about his own people. For this reason, it is stated, Nor was there a feeble person, or one who stumbled;6 for the verb lsk, kashal, has both these meanings. But I prefer taking it simply in this sense, That whilst Egypt was hastening to destruction, the people of God were vigorous, and free from every malady. When it is said, He brought them forth, and when it is afterwards added, in his tribes, there is a change of the number, which is quite common in the Hebrew language. Some refer the word his to God; but this I am afraid is too forced.
38. Egypt rejoiced at their departure. The Psalmist sets forth the power of God from the additional circumstance, that the Egyptians willingly allowed the chosen people to depart, when yet nothing was farther from their intention. Although they wished them destroyed a hundred times, yet they thought that they had the wolf by the ears, as we say; 7 and thus the fear of revenge made them more determined to blot out the memory of that people. Whence it follows, that when they all at once laid aside their former purpose, it was a secret work of divine providence. 8 To the same effect is the statement in the preceding verse, that they were brought forth with gold and silver. The Egyptians could never have had the heart voluntarily to strip themselves, to enrich those whom they would have willingly deprived of life. This was then the bounty of God, in whose hand, and at whose disposal, are all the riches of the world. He might have taken by force from the Egyptians what he had given them; but he bowed their hearts, so that of their own accord they denuded themselves. The expression, for their terror had fallen upon them, is to be understood passively; for the Israelites were not afraid of the Egyptians, but, on the contrary, were terrible to them. Nor does the prophet speak of an ordinary fear. A little before fear had stirred them up to cruelty and tyranny; but as even to that day, they had endeavored, with indomitable audacity, to shake off all fear, God suddenly laid them prostrate by the extraordinary terror which fell upon them. It is, therefore, here justly reckoned among the displays of the wonderful power of God, that he subdued the impetuous fury with which the Egyptians boiled before, that they might allow those to depart free, whom they had determined to handle rudely, and to waste in servile employments; which was like rendering sheep terrible to wolves.
