And Jehovah did so: a vast swarm of flies came upon Pharaoh's palace and into the homes of his servants; and all the land of Egypt was ruined by the swarms of flies. Then Pharaoh called for Moses and Aaron and said, "I will let you go that you may offer a sacrifice to Jehovah your God in the wilderness; only you must not go far away. Pray for me." Moses replied, "I will go out and will pray to Jehovah that the swarms of flies may depart from Pharaoh, from his servants and from his people to-morrow; only let not Pharaoh again act deceitfully by refusing to let the people go to offer a sacrifice to Jehovah." So Moses went out from Pharaoh and prayed to Jehovah. And Jehovah did as Moses asked; but this time also Pharaoh was stubborn and would not let the people go. Then Jehovah said to Moses, "Go to Pharaoh and tell him, 'Jehovah the God of the Hebrews commands: Let my people go that they may worship me. For if you refuse to let them go and still hold them, then the power of Jehovah will bring a very severe pest upon your cattle which are in the field, upon the horses, the asses, the camels, the herds, and the flocks. But Jehovah will make a difference between the cattle of Israel and the cattle of Egypt, and not one that belongs to the Israelites shall die.'" So Jehovah set a fixed time, saying, "To-morrow Jehovah will do this in the land." Jehovah did this on the next day, and all the cattle of the Egyptians died; but none of the cattle of the Israelites. Then Pharaoh sent and found that not even one of the cattle of the Israelites was dead; but Pharaoh was stubborn and would not let the people go. Then Jehovah said to Moses, "Get up early in the morning and stand before Pharaoh, and say to him,'Jehovah, the God of the Hebrews, commands: Let my people go, that they may worship me. Do you still set yourself against my people, so that you will not let them go? To-morrow about this time I will send down a very heavy fall of hail, such as has not been in Egypt from the day that it became a nation until now.'" So Jehovah sent down hail upon the land of Egypt, and the lightning flashing in the midst of the hail was very severe, such as had not been before in all Egypt since it became a nation. Through the whole land of Egypt the hail struck down everything that was in the field, both man and beast. The hail also struck down all the growing plants and broke all the trees in the fields. Only in the land of Goshen, where the Israelites were, there was no hail.
