42. They remembered not his hand in the day that he delivered them from the oppressor: 43. When he set his signs in Egypt, and his miracles in the field of Zoan.44. When he turned their rivers into blood; and their streams, that they could not drink.45. He sent among them a mixture which devoured them; and the frog which destroyed them.46. And he gave their fruit [or produce] to the caterpillar, and their labor to the grasshopper. 47. And he destroyed their vines with hail, and their wild fig-trees with hail stones. 48. And he gave up their cattle to the hail; and their flocks to thunderbolts.49. He sent upon them the fierceness of his wrath, fury, anger, and affliction, and sent evil angels among them.50. He made a way to his anger: he kept not their soul from death, and shut up their cattle to the pestilence.51. And he smote all the first-born in Egypt: the first-fruits of their strength in the tents of Ham.
42. They remembered not his hand. The sacred writer still continues to upbraid the Israelites; for the simple remembrance of God's benefits might have restrained them, had they not wilfully and perversely forgotten whatever they had experienced. From this impious forgetfulness proceed waywardness and all rebellion. The hand of God, as is well known, is by the figure metonomy taken for his power. In the deliverance of the chosen tribes from Egypt here celebrated, the hand of God was stretched forth in a new and an unusual manner. And their impiety, against which the prophet now inveighs, was rendered the more detestable, from the fact that they accounted as nothing, or soon forgat, that which no length of time ought to have effaced from their memory. Farther, he recounts certain examples of the power of God, which he calls first signs, and then miracles, (verse 43,) that, by the recital of these, he may again rebuke the shameful stupidity of the people. By both these words he expresses the same thing; but in the second clause of the verse, the word miracles gives additional emphasis, implying that, by such strange and unheard-of events, the Egyptians had at that time been stricken with such terror as ought not to have vanished so speedily from the minds of the Israelites.
44. When he turned their rivers into blood. The Psalmist does not enumerate in their order the miracles by which God gave evidence of his power in the deliverance of his people. He considered it enough to bring to their remembrance the well-known histories of these events, which would be sufficient to lay open the wickedness and ingratitude with which they were chargeable; nor is it necessary for us to stay long on these things, since the narrative of Moses gives a more distinct and fuller account of what is here briefly stated. Only I would have my readers to remember that, although God often punished the sins of the heathen by sending upon them hail and other calamities, yet all the plagues which at that time were inflicted upon the Egyptians were of an extraordinary character, and such as were previously unheard-of. A variety of words is therefore employed to enhance these memorable instances of the vengeance of God, as that he sent upon them the fierceness of his wrath, fury, anger, and affliction This accumulation of words is intended to awaken minds which are asleep to a discovery of so many miracles, of which both the number and the excellence might be perceived even by the blind themselves.
In the last place, it is added that God executed these judgments by angels. Although God has, according as it has pleased him, established certain laws, both in heaven and on earth, and governs the whole order of nature in such a manner as that each creature has assigned to it its own peculiar office; yet whenever it seems good to him he makes use of the ministration of angels for executing his commands, not by ordinary or natural means, but by his secret power, which to us is incomprehensible. Some think that devils are here spoken of, because the epithet evil or hurtful is applied to angel. This opinion I do not reject; but the ground upon which they rest it has little solidity. They say that as God dispenses his benefits to us by the ministry of elect angels, so he also executes his wrath by the agency of reprobate angels, as if they were his executioners. This I admit is partly true; but I deny that this distinction is always observed. Many passages of Scripture can be quoted to the contrary. When the army of the Assyrians laid siege to the holy city Jerusalem, who was it that made such havoc among them as compelled them to raise the siege, but the angel who was appointed at that time for the defense of the Church? (2 Kings 19:35.) In like manner, the angel who slew the first-born in Egypt (Exodus 11:5) was not only a minister and an executor of the wrath of God against the Egyptians, but also the agent employed for preserving the Israelites. On the other hand, although the kings of whom Daniel speaks were avaricious and cruel, or rather robbers, and turned all things upside down, yet the Prophet declares, (chapter 20:13,) that holy angels were appointed to take charge of them. It is probable that the Egyptians were given over and subjected to reprobate angels, as they deserved; but we may simply consider the angels here spoken of as termed evil, on account of the work in which they were employed, -- because they inflicted upon the enemies of the people of God terrible plagues to repress their tyranny and cruelty. In this way, both the heavenly and elect angels, and the fallen angels, are justly accounted the ministers or executors of calamity; but they are to be regarded as such in different senses. The former yield a prompt and willing obedience to God; but the latter, as they are always eagerly intent upon doing mischief, and would, if they could, turn the whole world upside down, are fit instruments for inflicting calamities upon men.
50. He made a way to his anger. To take away all excuse from this ungrateful people, whom the most evident and striking proofs of the goodness of God which were presented before their eyes could not keep in their obedience to him, it is here again repeated that the wrath of God overflowed Egypt like an impetuous torrent. The miracle adverted to is the last which was there wrought, when God, by the powerful hand of his angel, slew, in one night, all the first-born of Egypt. According to a common and familiar mode of speaking in the Hebrew language, the first-born are called the beginning, or the first-fruits of strength. Although the old advance to death as they decline in years, yet as they are in a manner renewed in their offspring, and thus may be said to recover their decayed strength, the term strength is applied to their children. And the first-born are called the beginning or the first-fruits of this strength, as I have explained more at large on Genesis 49:3. The houses of Egypt are called the tents of Ham, because Misraim, who gave the name to the country, was the son of Ham, Genesis 10:6. Farther, there is here celebrated the free love of God towards the posterity of Shem, as manifested in his preferring them to all the children of Ham, although they were possessed of no intrinsic excellence which might render them worthy of such a distinction.
