New American Standard Bible (NASB)
Exodus 10
24 Then Pharaoh called to Moses, and said, "Go, serve the Lord; only let your flocks and your herds be detained. Even your little ones may go with you."
25 But Moses said, "You must also let us have sacrifices and burnt offerings, that we may sacrifice them to the Lord our God.
26 Therefore, our livestock too shall go with us; not a hoof shall be left behind, for we shall take some of them to serve the Lord our God. And until we arrive there, we ourselves do not know with what we shall serve the Lord."
27 But the Lord hardened Pharaoh’s heart, and he was not willing to let them go.
28 Then Pharaoh said to him, "Get away from me! Beware, do not see my face again, for in the day you see my face you shall die!"
29 Moses said, "You are right; I shall never see your face again!"
Exodus 11
1 Now the Lord said to Moses, "One more plague I will bring on Pharaoh and on Egypt; after that he will let you go from here. When he lets you go, he will surely drive you out from here completely.
2 Speak now in the hearing of the people that each man ask from his neighbor and each woman from her neighbor for articles of silver and articles of gold."
3 The Lord gave the people favor in the sight of the Egyptians. Furthermore, the man Moses himself was greatly esteemed in the land of Egypt, both in the sight of Pharaoh’s servants and in the sight of the people.
4 Moses said, "Thus says the Lord, ’About midnight I am going out into the midst of Egypt,
5 and all the firstborn in the land of Egypt shall die, from the firstborn of the Pharaoh who sits on his throne, even to the firstborn of the slave girl who is behind the millstones; all the firstborn of the cattle as well.
