God brings a plague of darkness upon Egypt but Pharaoh still refuses to concede to God’s will (Exodus 10:21 – 10:29).
After the devastating plague of locusts, God said to Moses, “Stretch out your hand toward the sky so that darkness spreads over Egypt – darkness that can be felt.” So Moses stretched out his hand toward the sky and total darkness covered all Egypt for three days. No one could see anyone else or move about for three days. Yet all the Israelites had light in the places where they lived. Pharaoh summoned Moses and said, “Go, worship your god. Even your women and children may go with you. Only leave your flocks and herds behind.” But Moses said, “You must allow us to have sacrifices and burnt offerings to present to the Lord our God. Our livestock must go with us, not a hoof is to be left behind.
