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.

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.

"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 (Psalm 8:3; Luke 11:20, cf. Exodus 31:18). Consequently this miracle also made no impression upon Pharaoh.

And the magicians did so with their enchantments to bring forth lice, but they {e} could not: so there were lice upon man, and upon beast.

(e) God confounded their wisdom and authority in a thing most vile.

8:18 And the magicians did so - That is, endeavoured to do so.

8:16-19 These lice were produced out of the dust of the earth; out of any part of the creation God can fetch a scourge, with which to correct those who rebel against him. Even the dust of the earth obeys him. These lice were very troublesome, as well as disgraceful to the Egyptians, whose priests were obliged to take much pains that no vermin ever should be found about them. All the plagues inflicted on the Egyptians, had reference to their national crimes, or were rendered particularly severe by their customs. The magicians attempted to imitate it, but they could not. It forced them to confess, This is the finger of God! The check and restraint put upon us, must needs be from a Divine power. Sooner or later God will force even his enemies to acknowledge his own power. Pharaoh, notwithstanding this, was more and more obstinate.
