The LORD said to Moses, "Yet one plague more I will bring upon Pharaoh and upon Egypt; afterwards he will let you go hence; when he lets you go, he will drive you away completely.
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 all the first-born in the land of Egypt shall die, from the first-born of Pharaoh who sits upon his throne, even to the first-born of the maidservant who is behind the mill; and all the first-born of the cattle.
But against any of the people of Israel, either man or beast, not a dog shall growl; that you may know that the LORD makes a distinction between the Egyptians and Israel.
And all these your servants shall come down to me, and bow down to me, saying, `Get you out, and all the people who follow you.' And after that I will go out." And he went out from Pharaoh in hot anger.
Moses and Aaron did all these wonders before Pharaoh; and the LORD hardened Pharaoh's heart, and he did not let the people of Israel go out of his land.
