Expositor's Bible Commentary (Nicoll)
Exodus 8:20-32
THE FOURTH PLAGUE.
When the third plague had died away, when the sense of reaction and exhaustion had replaced agitation and distress, and when perhaps the fear grew strong that at any moment a new calamity might befal the land as abruptly as the last, God orders a solemn and urgent appeal to be made to the oppressor. And the same occurs three times: after each plague which arrives unexpectedly the next is introduced by a special warning. On each of these occasions, moreover, the appeal is made in the morning, at the hour when reason ought to be clearest and the passions least agitating; and this circumstance is perhaps alluded to in the favourite phrase of Jeremiah when he would speak of condescending earnestness--"I sent my prophets, rising up early and sending them" (Jeremiah 25:4, Jeremiah 26:5, Jeremiah 29:19, and many more; cf. also Jeremiah 7:13, and 2 Chronicles 36:15). So far is the Scripture from regarding Pharaoh as propelled by destiny, as by a machine, down iron grooves to ruin.
We have now come to the group of plagues which inflict actual bodily damage, and not inconvenience and humiliation only: the dogfly (or beetle); the murrain among beasts, which was a precursor of the crowning evil that struck at human life; and the boils. Of the fourth plague the precise nature is uncertain. There is a beetle which gnaws both man and beast, destroys clothes, furniture, and plants, and even now they "are often seen in millions" (Munk, Palestine, p. 120). "In a few minutes they filled the whole house.... Only after the most laborious exertions, and covering the floor of the house with hot coals, they succeeded in mastering them. If they make such attacks during the night, the inmates are compelled to give up the houses, and little children or sick persons, who are unable to rise alone, are then exposed to the greatest danger of life" (Pratte, Abyssinia, p. 143, in Kalisch).
Now, this explanation has one advantage over that of dogflies--that special mention is made of their afflicting "the ground whereon they are" (Exodus 8:21), which is less suitable to a plague of flies. But it may be that no one creature is meant. The Hebrew word means "a mixture." Jewish interpreters have gone so far as to make it mean "all kinds of noxious animals and serpents and scorpions mixed together," and although it is palpably absurd to believe that Pharaoh should have survived if these had been upon him and upon his servants, yet the expression "a mixture," following after one kind of vermin had tormented the land, need not be narrowed too exactly. With deliberate particularity the king was warned that they should come "upon thee, and upon thy servants, and upon thy people, and into thine houses, and the houses of the Egyptians shall be full of [them[15]], and also the ground whereon they are."
It has been supposed, from the special mention of the exemption of the land of Goshen, that this was a new thing. We have seen reason, however, to think otherwise, and the emphatic assertion now made is easy to understand. The plague was especially to be expected in low flat ground: the king may not even have been aware of the previous freedom of Israel; and in any case its importance as an evidence had not been pressed upon him. The spirit of the seventy-eighth Psalm, though not perhaps any one specific phrase, contrasts the earlier as well as the later plagues with the protection of His own people, whom He led like sheep (Psalms 78:42).
After the appointed interval (the same which Pharaoh had indicated for the removal of the frogs) the plague came. We are told that the land was corrupted, but it is significant that more stress is laid upon the suffering of Pharaoh and his court in the event than in the menace. It came home to himself more cruelly than any former plague, and he at once attempted to make terms: "Go ye, sacrifice to your God in the land." It is a natural speech, at first not asking to be trusted as before by getting relief before the Hebrews actually enjoy their liberty; and yet conceding as little as possible, and in hot haste to have that little done and the relief obtained. They may even serve their God on the sacred soil, so completely has He already defeated all His rivals. But this was not what was demanded; and Moses repeated the claim of a three days' journey, basing it upon the ground, still more insulting to the national religion, that "We will sacrifice to Jehovah our God the abomination of the Egyptians," that is to say, sacred animals, which it is horror in their eyes to sacrifice. Any faith in his own creed which Pharaoh ever had is surrendered when this argument, instead of making their cause hopeless, forces him to yield--adding, however, like a thoroughly weak man who wishes to refuse but dares not, "only ye shall not go very far away: intreat for me." And again Moses concedes the point, with only the courteous remonstrance, "But let not Pharaoh deal deceitfully any more."
It is necessary to repeat that we have not a shred of evidence that Moses would have violated his compact and failed to return: it would have sufficed as a first step to have asserted the nationality of his people and their right to worship their own God: all the rest would speedily have followed. But the terms which were rejected again and again did not continue for ever to bind the victorious party: the story of their actual departure makes it plain that both sides understood it to be a final exodus; and thence came the murderous pursuit of Pharaoh (cf. Exodus 15:9), which in itself would have cancelled any compact which had existed until then.
FOOTNOTES:
[15] The Revised Version has "swarms of flies," which is clearly an attempt to meet the case. But it is worth notice that in the Psalms the expression was twice rendered "divers kinds of flies" (Psalms 78:45, Psalms 105:31, A.V.) The word occurs only of this plague.
