(21) Then יהוה said to Moses, “Hold out your arm toward the sky that there may be darkness upon the land of Egypt, a darkness that can be touched.” (22) Moses held out his arm toward the sky and thick darkness descended upon all the land of Egypt for three days. (23) People could not see one another, and for three days no one could move about; but all the Israelites enjoyed light in their dwellings. (24) Pharaoh then summoned Moses and said, “Go, worship יהוה ! Only your flocks and your herds shall be left behind; even your dependents may go with you.” (25) But Moses said, “You yourself must provide us with sacrifices and burnt offerings to offer up to our God יהוה; (26) our own livestock, too, shall go along with us—not a hoof shall remain behind: for we must select from it for the worship of our God יהוה; and we shall not know with what we are to worship יהוה until we arrive there.” (27) But יהוה stiffened Pharaoh’s heart and he would not agree to let them go. (28) Pharaoh said to him, “Be gone from me! Take care not to see me again, for the moment you look upon my face you shall die.” (29) And Moses replied, “You have spoken rightly. I shall not see your face again!”
