Exodus 10:1-5

1And Jehovah said to Moses, Go in unto Pharaoh; for I have hardened his heart, and the heart of his bondmen, that I might do these my signs in their midst,

2and that thou mightest tell in the ears of thy son and thy son's son what I have wrought in Egypt, and my signs which I have done among them; and ye shall know that I am Jehovah.

3And Moses and Aaron came to Pharaoh, and said to him, Thus saith Jehovah the 1God of the Hebrews: How long dost thou refuse to humble thyself before me? let my people go, that they may serve me.

4For, if thou refuse to let my people go, behold, I will to-morrow bring locusts into thy borders;

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;
