Adam Clarke

On Exodus 8:18

The magicians did so - That is, They tried the utmost of their skill, either to produce these insects or to remove this plague; but they could not, no juggling could avail here, because insects must be produced which would stick to and infix themselves in man and beast, which no kind of trick could possibly imitate; and to remove them, as some would translate the passage, was to their power equally impossible. If the magicians even acted by spiritual agents, we find from this case that these agents had assigned limits, beyond which they could not go; for every agent in the universe is acting under the direction or control of the Almighty.

Jamieson, Fausset & Brown

On Exodus 8:16-19

PLAGUE OF LICE. (Exo 8:16-19)

smite the dust of the land, &c. - Aaron's rod, by the direction of Moses, who was commanded by God, was again raised, and the land was filled with gnats, mosquitoes--that is the proper meaning of the original term. In ordinary circumstances they embitter life in Eastern countries, and therefore the terrible nature of this infliction on Egypt may be imagined when no precautions could preserve from their painful sting. The very smallness and insignificance of these fierce insects made them a dreadful scourge. The magicians never attempted any imitation, and what neither the blood of the river nor the nuisance of the frogs had done, the visitation of this tiny enemy constrained them to acknowledge "this is the finger of God"--properly "gods," for they spoke as heathens.

John Gill

On Exodus 8:18

And the magicians did so with their enchantments, to bring forth lice,.... They made use of their magical art, and juggling tricks they were masters of, to produce the like sort of creatures, or at least to make such appear, or seem to appear, to the eyes of men:

but they could not; God would not suffer them to do it, to impose upon Pharaoh, and deceive him and the Egyptians any longer; and a stop is put to them, when such small and despicable creatures were produced, the more to put them to shame and confusion, and to show that what they did before was not real, and that what they did in appearance was only by divine permission:

so there were lice upon man and upon beast; these lay in great numbers on both, biting and distressing them in a most terrible manner; for as the magicians could not produce such creatures, it was not in their power to remove them.

Keil & Delitzsch

On Exodus 8:18-19

"The magicians did so with their enchantments (i.e., smote the dust with rods), to bring forth gnats, but could not." The cause of this inability is hardly to be sought for, as Knobel supposes, in the fact that "the thing to be done in this instance, was to call creatures into existence, and not merely to call forth and change creatures and things in existence already, as in the case of the staff, the water, and the frogs." For after this, they could neither call out the dog-flies, nor protect their own bodies from the boils; to say nothing of the fact, that as gnats proceed from the eggs laid in the dust or earth by the previous generation, their production is not to be regarded as a direct act of creation any more than that of the frogs. The miracle in both plagues was just the same, and consisted not in a direct creation, but simply in a sudden creative generation and supernatural multiplication, not of the gnats only, but also of the frogs, in accordance with a previous prediction. The reason why the arts of the Egyptians magicians were put to shame in this case, we have to seek in the omnipotence of God, restraining the demoniacal powers which the magicians had made subservient to their purposes before, in order that their inability to bring out these, the smallest of all creatures, which seemed to arise as it were from the dust itself, might display in the sight of every one the impotence of their secret arts by the side of the almighty creative power of the true God. This omnipotence the magicians were compelled to admit: they were compelled to acknowledge, "This is the finger of God." "But they did not make this acknowledgment for the purpose of giving glory to God Himself, but simply to protect their own honour, that Moses and Aaron might not be thought to be superior to them in virtue or knowledge. It was equivalent to saying, it is not by Moses and Aaron that we are restrained, but by a divine power, which is greater than either" (Bochart). The word Elohim is decisive in support of this view. If they had meant to refer to the God of Israel, they would have used the name Jehovah. The "finger of God" denotes creative omnipotence (Psa 8:3; Luk 11:20, cf. Exo 31:18). Consequently this miracle also made no impression upon Pharaoh.

Matthew Henry

On Exodus 8:16-19

Here is a short account of the plague of lice. It does not appear that any warning was given of it before. Pharaoh's abuse of the respite granted to him might have been a sufficient warning to him to expect another plague: for if the removal of an affliction harden us, and so we lose the benefit of it, we may conclude it goes away with a purpose to return or to make room for a worse. Observe,

I. How this plague of lice was inflicted on the Egyptians, Exo 8:16, Exo 8:17. The frogs were produced out of the waters, but these live out of the dust of the earth; for out of any part of the creation God can fetch a scourge, with which to correct those that rebel against him. He has many arrows in his quiver. Even the dust of the earth obeys him. "Fear not then, thou worm Jacob, for God can use thee as a threshing instrument, if he please," Isa 41:14, Isa 41:15. These lice, no doubt, were extremely vexatious, as well as scandalous, to the Egyptians. Though they had respite, they had respite but awhile, Rev 11:14. The second woe was past, but behold the third woe came very quickly.

II. How the magicians were baffled by it, Exo 8:18. They attempted to imitate it, but they could not. When they failed in this, it should seem they attempted to remove it; for it follows, So there were lice upon man and beast, in spite of them. This forced them to confess themselves overpowered: This is the finger of God (Exo 8:19); that is, "This check and restraint put upon us must needs be from a divine power." Note, 1. God has the devil in a chain, and limits him both as a deceiver and as a destroyer; hitherto he shall come, but no further. The devil's agents when God permitted them, could do great things; but when he laid an embargo upon them, though but with his finger, they could do nothing. The magicians' inability, in this less instance, showed whence they had their ability in the former instances which seemed greater, and that they had no power against Moses but what was given them from above. 2. Sooner or later God will extort, even from his enemies, an acknowledgment of his own sovereignty and over-ruling power. It is certain they must all (as we say) knock under at last, as Julian the apostate did, when his dying lips confessed, Thou hast overcome me, O thou Galilean! God will not only be too hard for all opposers, but will force them to own it.

III. How Pharaoh, notwithstanding this, was made more and more obstinate (Exo 8:19); even those that had deceived him now said enough to undeceive him, and yet he grew more and more obstinate. Even the miracles and the judgments were to him a savour of death unto death. Note, Those that are not made better by God's word and providences are commonly made worse by them.

Tyndale Study Notes

On Exodus 8:16-18

8:16-19 The third plague was the plague of gnats. The word translated “gnats” is very general. Technical Old Testament dictionaries often translate it as “vermin.” The English term “bugs” would come close. The whole land was infested with insects of one sort or another.
