20 But the Lord hardened Pharaoh’s heart, and he did not let the Israelites go.
21 Then the Lord said to Moses, “Stretch out your hand toward heaven, and there will be darkness over the land of Egypt, a darkness that can be felt.”
22 So Moses stretched out his hand toward heaven, and there was thick darkness throughout the land of Egypt for three days.
23 One person could not see another, and for three days they did not move from where they were. Yet all the Israelites had light where they lived.
24 Pharaoh summoned Moses and said, “Go, worship Yahweh. Even your families may go with you; only your flocks and herds must stay behind.”
25 Moses responded, “You must also let us have sacrifices and burnt offerings to prepare for Yahweh our God.
26 Even our livestock must go with us; not a hoof will be left behind because we will take some of them to worship Yahweh our God. We will not know what we will use to worship Yahweh until we get there.”
