The Lord told Moses he would bring one more plague on Pharaoh and Egypt, and that after it Pharaoh would let them go, and indeed drive them out completely. God commanded that every man and woman ask their Egyptian neighbors for silver and gold jewelry. The Lord gave the people favor in the sight of the Egyptians, and Moses himself was greatly esteemed in the land of Egypt, both by Pharaoh's servants and by the people.
Moses told Pharaoh that about midnight the Lord would go out through the midst of Egypt and every firstborn in the land would die, from the firstborn of Pharaoh who sat on his throne to the firstborn of the slave girl behind the mill, and also every firstborn of the animals. There would be a great cry throughout the land, such as there had never been before or would be again. But among the Israelites not even a dog would growl at man or beast, so that they would know that the Lord makes a distinction between Egypt and Israel.
Moses added that Pharaoh's servants would come down to bow before him and ask him to leave with all the people. After that he would go. And he went out from Pharaoh's presence in great anger.
The text closes with a note from the Lord to Moses: Pharaoh would not listen to them, so that his wonders might be multiplied in Egypt. Moses and Aaron had done all these wonders before Pharaoh, but the Lord had hardened his heart, and he did not let the Israelites go out of his land.
