Parallel
Exodus 10:5
Brenton's English Septuagint · Berean Standard Bible
And they shall cover the face of the earth, and thou shalt not be able to see the earth; and they shall devour all that is left of the abundance of the earth, which the hail has left you, and shall devour every tree that grows for you on the land.
They will cover the face of the land so that no one can see it. They will devour whatever is left after the hail and eat every tree that grows in your fields.
