Exodus 10:5-6

5and they shall cover the face of the land, so that ye will not be able to see the land; and they shall eat the residue of that which is escaped, which ye have remaining from the hail, and shall eat every tree which ye have growing in the field;

6and they shall fill thy houses, and the houses of all thy bondmen, and the houses of all the Egyptians; which neither thy fathers nor thy fathers' fathers have seen, since the day that they were upon the earth unto this day. And he turned and went out from Pharaoh.
