And Jehovah spoke to Moses, Say to Aaron, Take your staff and stretch out your hand over the waters of Egypt, over their streams, over their rivers, over their ponds, and over all their bodies of water, that they may become blood. And there shall be blood throughout all the land of Egypt, in vessels of both wood and stone.

Or else, if you refuse to let My people go, behold, tomorrow I will bring locusts into your territory.

And they shall cover the face of the earth, so that no one will be able to see the land; and they shall eat the rest of what is left, which remains to you from the hail, and they shall eat every tree which grows up for you out of the field.
