Exodus 10:19 DBY

¹⁷  And now, forgive, I pray you, my sin only this time, and intreat Jehovah your God that he may take away from me this death only!

¹⁸  And he went out from Pharaoh, and intreated Jehovah.

¹⁹  And Jehovah turned a very powerful west wind, which took away the locusts, and drove them into the Red Sea: there remained not one locust in all the borders of Egypt.

²⁰  And Jehovah made Pharaoh's heart stubborn, and he did not let the children of Israel go.

²¹  And Jehovah said to Moses, Stretch out thy hand toward the heavens, that there may be darkness in the land of Egypt -- so that one may feel darkness.
