Exodus 10:19-21

Douay-Rheims 1899 American Edition

¹⁹ And he made a very strong wind to blow from the west, and it took the locusts and cast them into the Red Sea: there remained not so much as one in all the coasts of Egypt.

²⁰ And the Lord hardened Pharao's heart, neither did he let the children of Israel go.

²¹ And the Lord said to Moses: Stretch out they hand towards heaven: and may there be darkness upon the land of Egypt, so thick that it may be felt.
