“Yahweh said to Moses, ‘One more plague shall I bring upon Pharaoh and upon Egypt; after that he shall send you forth from here. When he send forth, it shall be complete – he shall drive you out of here. Speak to the ears of the people: Let each man request of his fellow and each woman from her fellow silver vessels and gold vessels.’ Yahweh granted the people favor in the eyes of Egypt; moreover, the man Moses was very great in the land of Egypt, in the eyes of the servants of Pharaoh and in the eyes of the people.”
“Moses said, ‘So said Yahweh: At about midnight I shall go out in the midst of Egypt. Every firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne, to the firstborn of the maidservant who is behind the millstone, and all the firstborn of beast. There shall be a great outcry in the entire land of Egypt, such as there has never been and such as there shall never be again. But against all the Children of Israel, no dog shall whet its tongue, against neither man nor beast, so that you shall know that Yahweh will have differentiated between Egypt and Israel. Then all these servants of yours will come down to me and bow to me, saying: Leave – you and the entire people that follows you. After that, I will leave!’ And he left Pharaoh’s presence in a burning anger. Yahweh said to Moses, ‘Pharaoh will not heed you, so that My wonders may be multiplied in the land of Egypt.’ So Moses and Aaron performed all these wonders before Pharaoh, but Yahweh strengthened the heart of Pharaoh and he did not send out the Children of Israel from his land” (Ex 11:1-10).
