Exodus 10:27

25Moses said, “You must also give into our hand sacrifices and burnt offerings, that we may sacrifice to the LORD our God.

26Our livestock also shall go with us. Not a hoof shall be left behind, for of it we must take to serve the LORD our God; and we don’t know with what we must serve the LORD, until we come there.”

27But the LORD hardened Pharaoh’s heart, and he wouldn’t let them go.

28Pharaoh said to him, “Get away from me! Be careful to see my face no more; for in the day you see my face you shall die!”

29Moses said, “You have spoken well. I will see your face again no more.”
