Exodus.
Chapter 11.
And the LORD said to Moses, Yet will I bring one plague more upon Pharaoh, and upon Egypt; afterwards he will let you go hence: when he shall let you go, he shall surely thrust you out hence altogether. 
Speak now in the ears of the people, and let every man borrow of his neighbor, and every woman of her neighbor, jewels of silver, and jewels of gold. 
And the LORD gave the people favor in the sight of the Egyptians. Moreover, the man Moses was very great in the land of Egypt, in the sight of Pharaoh's servants, and in the sight of the people. 
And Moses said, Thus saith the LORD, About midnight will I go out into the midst of Egypt: 
And all the first-born in the land of Egypt shall die, from the first-born of Pharaoh that sitteth upon his throne, even to the first-born of the maid-servant that is behind the mill; and all the first-born of beasts. 
And there shall be a great cry throughout all the land of Egypt, such as there hath been none like it, nor shall be like it any more. 
But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how the LORD doth put a difference between the Egyptians and Israel. 
And all these thy servants shall come down to me, and bow down themselves to me, saying, Depart thou, and all the people that follow thee; and after that I will depart: and he went out from Pharaoh in a great anger. 
And the LORD said to Moses, Pharaoh will not hearken to you; that my wonders may be multiplied in the land of Egypt. 
And Moses and Aaron did all these wonders before Pharaoh; and the LORD hardened Pharaoh's heart, so that he would not let the children of Israel depart from his land.
