16 Then Pharaoh called for Moses and Aaron in haste, and he said, “I have sinned against the Lord your God, and against you.
17 Now therefore please forgive my sin again, and pray to the Lord your God, that he may also take away from me this death.”
18 Moses went out from Pharaoh, and prayed to the Lord.
19 The Lord turned an exceedingly strong west wind, which took up the locusts, and drove them into the Sea of Suf. There remained not one locust in all the borders of Egypt.
20 But the Lord hardened Pharaoh’s heart, and he didn’t let the children of Israel go.
21 The Lord said to Moses, “Stretch out your hand towards the sky, that there may be darkness over the land of Egypt, even darkness which may be felt.”
22 Moses stretched out his hand towards the sky, and there was a thick darkness in all the land of Egypt for three days.
