16. Wherefore Pharao in haste called Moses and Aaron, and said to them: I have sinned against the Lord your God, and against you.
17. But now forgive me my sin this time also, and pray to the Lord your God, that he take away from me this death.
18. And Moses going forth from the presence of Pharao, prayed to the Lord.
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.
