Exodus

And יהוה said to Moses, “I will bring but one more plague upon Pharaoh and upon Egypt; after that he shall let you go from here; indeed, when he lets you go, he will drive you out of here one and all.

Tell the people to borrow, each man from his neighbor and each woman from hers, objects of silver and gold.”

יהוה disposed the Egyptians favorably toward the people. Moreover, Moses himself “the man Moses.” See the Dictionary under ’ish. was much esteemed in the land of Egypt, among Pharaoh’s courtiers and among the people.

Moses said, “Thus says יהוה: Toward midnight I will go forth among the Egyptians,

and every [male] first-born in the land of Egypt shall die, from the first-born of Pharaoh who sits on his throne to the first-born of the slave girl who is behind the millstones; and all the first-born of the cattle.

And there shall be a loud cry in all the land of Egypt, such as has never been or will ever be again;

but not a dog shall snarl .” at any of the Israelites, at human or beast—in order that you may know that יהוה makes a distinction between Egypt and Israel.

“Then all these courtiers of yours shall come down to me and bow low to me, saying, ‘Depart, you and all the people who follow you!’ After that I will depart.” And he left Pharaoh’s presence in hot anger.

Now יהוה had said to Moses, “Pharaoh will not heed you, in order that My marvels may be multiplied in the land of Egypt.”

Moses and Aaron had performed all these marvels before Pharaoh, but יהוה had stiffened the heart of Pharaoh so that he would not let the Israelites go from his land.
