Exodus 10:17-20

MLV(i) 17 Now therefore I beseech you, forgive my sin only this once and entreat Jehovah your* God, that he may only take away from me this death.
18 And he went out from Pharaoh and entreated Jehovah. 19 And Jehovah turned an exceedingly strong west wind, which took up the locusts and drove them into the Red Sea. There remained not one locust in all the border of Egypt. 20 But Jehovah hardened Pharaoh's heart and he did not let the sons of Israel go.
