Exodus 8:31 Meaning and Commentary

Exodus 8:31

And the Lord did according to the word of Moses
Did as he entreated him to do, as follows: and he removed the swarms of flies from Pharaoh, from his servants, and
from his people;
by what means is not said, whether by destroying them at once, as the frogs, or by driving them away with a wind, as the locusts afterwards: there remained not one;
the meaning is not, not one swarm of flies, but not one fly, there was not one left; which looks as if it was in the latter way that they were removed, since, if in the former, they would have remained, though dead, as the frogs did, for a little while.

Exodus 8:31 In-Context

29 And Moses said, I then will go forth from thee and pray to God, and the dog-fly shall depart both from thy servants, and from thy people to-morrow. Do not thou, Pharao, deceive again, so as not to send the people away to do sacrifice to the Lord.
30 And Moses went out from Pharao, and prayed to God.
31 And the Lord did as Moses said, and removed the dog-fly from Pharao, and from his servants, and from his people, and there was not one left.
32 And Pharao hardened his heart, even on this occasion, and he would not send the people away.
