17. And they did so; for Aaron stretched out his hand with his rod, and smote the dust of the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.
18. And the magicians did so with their enchantments to bring forth lice, but they could not: so there were lice upon man, and upon beast.
19. Then the magicians said unto Pharaoh, This is the finger of God: and Pharaoh's heart was hardened, and he hearkened not unto them; as the LORD had said.
20. And the LORD said unto Moses,
21. Else, if you will not let my people go, behold, I will send swarms of flies upon you, and upon your servants, and upon your people, and into your houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground on which they are.
22. 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 you may know that I am the LORD in the midst of the earth.
23. And I will put a division between my people and your people: tomorrow shall this sign be.
24. And the LORD did so; and there came a grievous swarm of flies into the house of Pharaoh, and into his servants' houses, and into all the land of Egypt: the land was corrupted by reason of the swarm 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 is not proper so to do; for we shall sacrifice the abomination of the Egyptians before their eyes, and will they not stone us?
27. We will go three days' journey into the wilderness, and sacrifice to the LORD our God, as he shall command us.
28. And Pharaoh said, I will let you go, that you may sacrifice to the LORD your God in the wilderness; only you shall not go very far away: entreat for me.
29. And Moses said, Behold, I go out from you, and I will entreat the LORD that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow: but let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the LORD.
30. And Moses went out from Pharaoh, and entreated the LORD.
31. 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.
32. And Pharaoh hardened his heart at this time also, neither would he let the people go.
