Exodus 7:19 Then the LORD said to Moses, "Say to Aaron, 'Take your staff and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their reservoirs of water, that they may become blood; and there will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.'"

Exodus 10:5 'They shall cover the surface of the land, so that no one will be able to see the land. They will also eat the rest of what has escaped-- what is left to you from the hail-- and they will eat every tree which sprouts for you out of the field.

Exodus 10:15 For they covered the surface of the whole land, so that the land was darkened; and they ate every plant of the land and all the fruit of the trees that the hail had left. Thus nothing green was left on tree or plant of the field through all the land of Egypt. (NASB ©1995)
