21 Or else, if you will not let my people go, behold, I will send swarms of flies on you and your servants and your people, and into your houses. And the houses of the Egyptians shall be filled with swarms of flies, and also the ground on which they stand. 22 But on that day gI will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, hthat you may know that I am the Lord in the midst of the earth.5 23 Thus I will put a division6 between my people and your people. Tomorrow this sign shall happen.” ’ ” 24 And the Lord did so. iThere came great swarms of flies into the house of Pharaoh and into his servants’ houses. Throughout all the land of Egypt the land was ruined by the swarms of flies.

25 Then Pharaoh called Moses and Aaron and said, “Go, sacrifice to your God within the land.” 26 But Moses said, “It would not be right to do so, for the offerings we shall sacrifice to the Lord our God are an jabomination to the Egyptians. If we sacrifice offerings jabominable to the Egyptians before their eyes, will they not stone us? 27 We must go kthree days’ journey into the wilderness and sacrifice to the Lord our God las he tells us.” 28 So Pharaoh said, “I will let you go to sacrifice to the Lord your God in the wilderness; only you must not go very far away. mPlead for me.” 29 Then Moses said, “Behold, I am going out from you and I will plead with the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow. Only let not Pharaoh ncheat again by not letting the people go to sacrifice to the Lord.” 30 So Moses went out from Pharaoh and prayed to the Lord. 31 And the Lord did as Moses asked, and removed the swarms of flies from Pharaoh, from his servants, and from his people; not one remained.
