13. And the Lord did according to the word of Moses, and the frogs died out of the houses, out of the courtyards and villages, and out of the fields.
14. [The people] gathered them together in heaps, and the land was loathsome and stank.
15. But when Pharaoh saw that there was temporary relief, he made his heart stubborn and hard and would not listen or heed them, just as the Lord had said.
16. Then the Lord said to Moses, Say to Aaron, Stretch out your rod and strike the dust of the ground, that it may become biting gnats or mosquitoes throughout all the land of Egypt.
17. And they did so; Aaron stretched out his hand with his rod and struck the dust of the earth, and there came biting gnats or mosquitoes on man and beast; all the dust of the land became biting gnats or mosquitoes throughout all the land of Egypt.
18. The magicians tried by their enchantments and secret arts to bring forth gnats or mosquitoes, but they could not; and there were gnats or mosquitoes on man and beast.
19. Then the magicians said to Pharaoh, This is the finger of God! But Pharaoh's heart was hardened and strong and he would not listen to them, just as the Lord had said.
20. Then the Lord said to Moses, Rise up early in the morning and stand before Pharaoh as he comes forth to the water; and say to him, Thus says the Lord, Let My people go, that they may serve Me.
21. Else, if you will not let My people go, behold, I will send swarms [of bloodsucking gadflies] upon you, your servants, and your people, and into your houses; and the houses of the Egyptians shall be full of swarms [of bloodsucking gadflies], and also the ground on which they stand.
22. But on that day I will sever and set apart the land of Goshen in which My people dwell, that no swarms [of gadflies] shall be there, so that you may know that I am the Lord in the midst of the earth.
23. And I will put a division and a sign of deliverance between My people and your people. By tomorrow shall this sign be in evidence.
24. And the Lord did so; and there came heavy and oppressive swarms [of bloodsucking gadflies] into the house of Pharaoh and his servants' houses; and in all of Egypt the land was corrupted and ruined by reason of the great invasion [of gadflies].
25. And Pharaoh called for Moses and Aaron, and said, Go, sacrifice to your God [here] in the land [of Egypt].
26. And Moses said, It is not suitable or right to do that; for the animals the Egyptians hold sacred and will not permit to be slain are those which we are accustomed to sacrifice to the Lord our God; if we did this before the eyes of the Egyptians, would they not stone us?
