Exodus 11:1-6

1 And 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.
2 Speak therefore secretly in the ears of the people, and let every one ask of his neighbour jewels of silver and gold, and raiment.
3 And 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.
4 And Moses said, These things saith the Lord, About midnight I go forth into the midst of Egypt.
5 And 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.
6 And 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.

Exodus 11:1-6 Meaning and Commentary

INTRODUCTION TO EXODUS 11

Moses having an intimation from the Lord that one plague more would be brought on Pharaoh, and then he would let Israel go, when they should borrow of their neighbours jewels of gold and silver, the people being in great favour with the Egyptians, Ex 11:1-3, he declares to Pharaoh, before he went out of his presence, the slaying of all the firstborn in Egypt, which would issue in the dismission of Israel, and then he went out from him in great anger, Ex 11:4-8, but still Pharaoh would not hearken, and his heart was hardened, and he refused again to let Israel go, Ex 10:9,10.
