Moreover Moses was very great in the land of Egypt: both in the sight of Pharao, and also in the sight of the people. And Moses said: thus sayeth the LORD. About midnight will I go out among the Egyptians, and all the firstborn in the land of Egypt shall die: even from the firstborn of Pharao that sitteth on his seat, unto the firstborn of the maidservant that is in the mill, and all the firstborn of the cattle. And there shall be a great cry thorowout all the land of Egypt: so that there was never none like nor shall be. And among all the children of Israel shall not a dog move his tongue, nor yet man or beast: that ye may know, how the LORD putteth a difference between the Egyptians and Israel. And all these thy servants shall come down unto me, and fall before me and say: get thee out and all the people that are under thee, and then will I depart.

And Moses and Aaron did all these wonders before Pharao. But the LORD hardened Pharao's heart, so that he would not let the children of Israel go out of his land. Chapter .xij.
