Exodus 10:4-7King James Version (KJV)
4 Else, if thou refuse to let my people go, behold, to morrow will I bring the locusts into thy coast:
5 And they shall cover the face of the earth, that one cannot be able to see the earth: and they shall eat the residue of that which is escaped, which remaineth unto you from the hail, and shall eat every tree which groweth for you out of the field:
6 And they shall fill thy houses, and the houses of all thy servants, 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 himself, and went out from Pharaoh.
7 And Pharaoh's servants said unto him, How long shall this man be a snare unto us? let the men go, that they may serve the Lord their God: knowest thou not yet that Egypt is destroyed?
