Exodus 10:3-7

And Moses and Aaron went in unto Pharaoh, and said unto him, Thus saith Jehovah, the God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me. Else, if thou refuse to let my people go, behold, to-morrow will I bring locusts into thy border: and they shall cover the face of the earth, so that one shall not 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: and thy houses shall be filled, and the houses of all thy servants, and the houses of all the Egyptians; as 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. 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 Jehovah their God: knowest thou not yet that Egypt is destroyed?
