20 Then Jehovah said to Moses, Rise up early in the morning, and present yourself before Pharaoh as he is going out to the water, and say to him, Thus says Jehovah, Let My people go that they may serve Me.
21 For if you will not let My people go, then I will at once send swarms of flies against you and against your servants and against your people and against your houses; and the houses of the Egyptians will be full of swarms of flies, as well as the ground on which they are.
22 But on that day I will set apart the land of Goshen, where My people are staying, so that no swarms of flies will be there, so that you may know that I am Jehovah in the midst of the land.
23 And I will put redemption between My people and your people. Tomorrow this sign shall occur.
24 And Jehovah did so; and heavy swarms of flies came into the house of Pharaoh and into his servants’ houses, and throughout the land of Egypt the land was ruined because of the swarms of flies.
25 And Pharaoh called for Moses and for Aaron and said, Go, sacrifice to your God in the land.
26 And Moses said, It would not be right to do so, for we will sacrifice to Jehovah our God what is an abomination to the Egyptians. If we sacrifice what is an abomination to the Egyptians before their eyes, will they not stone us?
27 We must go a three days’ journey into the wilderness and sacrifice to Jehovah our God just as He commands us.
28 And Pharaoh said, I will let you go that you may sacrifice to Jehovah your God in the wilderness; only you shall not go very far away. Make entreaty for me.
29 And Moses said, I am now going out from you, and I will entreat Jehovah that the swarms of flies would depart from Pharaoh, from his servants, and from his people tomorrow; only do not let Pharaoh deal deceitfully anymore by not letting the people go to sacrifice to Jehovah.
30 So Moses went out from Pharaoh and entreated Jehovah.
31 And Jehovah did according to the word of Moses, and He removed the swarms of flies from Pharaoh, from his servants, and from his people; not one remained.
32 However Pharaoh hardened his heart at this time also, and he did not let the people go.
