In Exodus 9, three more plagues occur in Egypt due to the refusal of Pharaoh to let the Israelites leave to worship their God. First was the death of all the livestock of the Egyptians, then boils broke out among all the men and animals in Egypt, and then God sent the worst hailstorm ever to land on Egypt and crushed the fields and trees. Pharaoh summoned Moses and again asked him to pray to the Lord and tell Him that he would let the people go. Moses prayed and the the storm stopped, but Pharaoh again hardened his heart and he would not let the Israelites go. In Exodus 10, God sent two more plagues to Egypt , locusts which ate every remaining green plant and tree, and then complete darkness in which no one could see anyone else or leave his place for three days. Even after all these plagues, Pharaoh still hardened his heart and was not willing to let them go and worship. Pharaoh told Moses , "Get out of my sight! Make sure you do not appear before me again! " Moses replied, "Just as you say, I will never appear before you again."
