And the Lord said to Moses, "Rise up early in the morning, and stand before Pharaoh; lo, he cometh forth to the water; and say to him, 'Thus saith the Lord, Let my people go, that they may serve me. Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon thy servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are. And I will set apart in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am the {159} Lord in the midst of the earth. And I will put a division between my people and thy people: by to-morrow shall this sign be.'" And the Lord did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses: and in all the land of Egypt the land was corrupted by reason of the swarms of flies. And Pharaoh called for Moses and for Aaron, and said, "Go ye, sacrifice to your God in the land." And Moses said, "It is not right so to do; for we shall sacrifice the holy things of the Egyptians to the Lord our God: lo, shall we sacrifice the holy things of the Egyptians before their eyes, and will they not stone us? We will go three days' journey into the wilderness, and sacrifice to the Lord our God, as he shall command us." And Pharaoh said, "I will let you go, that ye may sacrifice to the Lord your God in the wilderness; only ye shall not go very far away: intreat for me." And Moses said, "Behold, I go out from thee, and I will intreat the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people, to-morrow: only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the Lord." And Moses went out from Pharaoh and intreated the Lord. And the Lord did according to the word of Moses; and he removed the swarms of flies from Pharaoh, from his servants, and from his people; there remained not one. And Pharaoh hardened his heart this time also, and he did not let the people go. {160} 5. THE PLAGUE OF CATTLE DISEASE. Then the Lord said unto Moses, "Go in to Pharaoh, and tell him, 'Thus saith the Lord, the God of the Hebrews, Let my people go that they may serve me. For if thou refuse to let them go, and wilt hold them still, behold, the hand of the Lord is upon thy cattle which are in the field, upon the horses, upon the asses, upon the camels, upon the herds, and upon the flocks: there shall be a very grievous distemper. And the Lord shall distinguish between the cattle of Israel and the cattle of Egypt: and there shall nothing die of all that belongeth to the children of Israel.'" And the Lord appointed a set time, saying, "To-morrow the Lord shall do this thing in the land."
