Exodus 11

God plans the tenth plague.
(The killing of all firstborn Egyptian children and animals)

11:1 And the LORD said unto 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.

11:2 Speak now in the ears of the people, and let every man borrow of his neighbour, and every woman of her neighbour, jewels of silver and jewels of gold.

11:3 And the LORD gave the people favour 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.

(11:2) Let every man borrow of his neighbour, and every woman of her neighbour, jewels of silver and jewels of gold.
Is it wrong to steal?

11:4 And Moses said, Thus saith the LORD, About midnight will I go out into the midst of Egypt:

(11:4-6) These verses clearly show that the mass murder of innocent children by God (see 12:29-30) was premeditated.

(11:4) About midnight will I go out into the midst of Egypt.

11:5 And all the firstborn in the land of Egypt shall die, from the first born of Pharaoh that sitteth upon his throne, even unto the firstborn of the maidservant that is behind the mill; and all the firstborn of beasts.

(11:5) And all the firstborn in the land of Egypt shall die, from the first born of Pharaoh that sitteth upon his throne, even unto the firstborn of the maidservant that is behind the mill; and all the firstborn of beasts.

11:6 And there shall be a great cry throughout all the land of Egypt, such as there was none like it, nor shall be like it any more.

(11:6) There shall be a great cry throughout all the land of Egypt.

11:7 But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the LORD doth put a difference between the Egyptians and Israel.

11:8 And all these thy servants shall come down unto me, and bow down themselves unto me, saying, Get thee out, and all the people that follow thee: and after that I will go out. And he went out from Pharaoh in a great anger.

(11:7)
That ye may know how that the LORD doth put a difference between the Egyptians and Israel
God will kill the Egyptian children to show that he puts "a difference between the Egyptians and Israel."

11:9 And the LORD said unto Moses, Pharaoh shall not hearken unto you; that my wonders may be multiplied in the land of Egypt.

(11:9) The LORD said unto Moses, Pharaoh shall not hearken unto you; that my wonders may be multiplied in the land of Egypt.
God explains to Moses that he has been hardening Pharaoh's heart so that Pharaoh will not let the Israelites go. God says that this way he'll be able to show off his latest signs and wonders (by murdering little children).

11:10 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 go out of his land.

(11:10) The LORD hardened Pharaoh's heart, so that he would not let the children of Israel go.
God hardens Pharaoh's heart one last time "so that he would not let the children of Israel go."
Who hardened the Pharaoh's heart?
