21 Yahweh said to Moses, “Stretch out your hand toward the sky, that there may be darkness over the land of Egypt, even darkness which may be felt.” 22 Moses stretched out his hand toward the sky, and there was a thick darkness in all the land of Egypt for three days. 23 They didn’t see one another, and nobody rose from his place for three days; but all the children of Israel had light in their dwellings.
24 Pharaoh called to Moses, and said, “Go, serve Yahweh. Only let your flocks and your herds stay behind. Let your little ones also go with you.”
25 Moses said, “You must also give into our hand sacrifices and burnt offerings, that we may sacrifice to Yahweh our God. 26 Our livestock also shall go with us. Not a hoof shall be left behind, for of it we must take to serve Yahweh our God; and we don’t know with what we must serve Yahweh, until we come there.”
27 But Yahweh hardened Pharaoh’s heart, and he wouldn’t let them go.28 Pharaoh 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!”
