Brenton Septuagint Translation
The Plague on the Firstborn Foretold
1And the Lord said to Moses, I will yet bring one plague upon Pharao and upon Egypt, and after that he will send you forth thence; and whenever he sends you forth with every thing, he will indeed drive you out. 2Speak therefore secretly in the ears of the people, and let every one ask of his neighbour jewels of silver and gold, and raiment. 3And the Lord gave his people favour in the sight of the Egyptians, and they lent to them; and the man Moses was very great before the Egyptians, and before Pharao, and before his servants.
4And Moses said, These things saith the Lord, About midnight I go forth into the midst of Egypt. 5And every first-born in the land of Egypt shall die, from the first-born of Pharao that sits on the throne, even to the first-born of the woman-servant that is by the mill, and to the first-born of all cattle. 6And there shall be a great cry through all the land of Egypt, such as has not been, and such shall not be repeated any more. 7But among all the children of Israel shall not a dog snarl with his tongue, either at man or beast; that thou mayest know how wide a distinction the Lord will make between the Egyptians and Israel. 8And all these thy servants shall come down to me, and do me reverence, saying, Go forth, thou and all the people over whom thou presidest, and afterwards I will go forth.
9And Moses went forth from Pharao with wrath. And the Lord said to Moses, Pharao will not hearken to you, that I may greatly multiply my signs and wonders in the land of Egypt. 10And Moses and Aaron wrought all these signs and wonders in the land of Egypt before Pharao; and the Lord hardened the heart of Pharao, and he did not hearken to send forth the children of Israel out of the land of Egypt.
