Exodus 10:19-21

New American Standard Bible

¹⁹ So the Lord shifted the wind to a very strong west wind, which picked up the locusts and drove them into the ^[a]Red Sea; not one locust was left in all the territory of Egypt. ²⁰ But ^(A)the Lord ^[b]hardened Pharaoh’s heart, and he did not let the sons of Israel go.

Darkness over the Land

²¹ Then the Lord said to Moses, “^(B)Reach out with your hand toward the sky, so that there may be darkness over the land of Egypt, even a darkness ^(C)which may be felt.”
