What does Exodus 10:15 mean?

For they covered the face of the whole earth, so that the land was darkened; and they did eat every herb of the land, and all the fruit of the trees which the hail had left: and there remained not any green thing, either tree or herb of the field, through all the land of Egypt.

For they covered the face of the whole earth, so that the land was darkened; and they did eat every herb of the land, and all the fruit of the trees which the hail had left: and there remained not any green thing in the trees, or in the herbs of the field, through all the land of Egypt.

For they covered the face of the whole earth, so that the land was darkened; and they did eat every herb of the land, and all the fruit of the trees which the hail had left: and there remained not any green thing, either tree or herb of the field, through all the land of Egypt.

For all the face of the earth was covered with them, so that the land was black; and every green plant and all the fruit of the trees which was untouched by the ice-storm they took for food: not one green thing, no plant or tree, was to be seen in all the land of Egypt.

and it covereth the eye of all the land, and the land is darkened; and it eateth every herb of the land, and all the fruit of the trees which the hail hath left, and there hath not been left any green thing in the trees, or in the herb of the field, in all the land of Egypt.'

And they covered the whole face of the earth, wasting all things. And the grass of the earth was devoured, and what fruits soever were on the trees, which the hail had left; and there remained not any thing that was green on the trees, or in the herbs of the earth, in all Egypt.

And they covered the face of the whole land, so that the land was darkened; and they ate every herb of the land, and all the fruit of the trees that the hail had left; and there remained not any green thing on the trees, and in the herbs of the field, throughout the land of Egypt.
