Forgive me yet my sin only this once, and pray unto the LORD your God that he may take away from me this death only. And he went out from Pharao and prayed unto the LORD, and the LORD turned the wind into a mighty strong west wind, and it took away the grasshoppers and cast them into the reed sea: so that there was not one grasshopper left in all the coasts of Egypt. But the LORD hardened Pharao's heart, so that he would not let the children of Israel go. And the LORD said unto Moses: Stretch out thy hand unto heaven, and let there be darkness upon the land of Egypt: even that they may feel the darkness. And Moses stretched forth his hand unto heaven, and there was a dark mist {thick darkness} upon all the land of Egypt three days long, so that no man saw another, neither rose up from the place where he was by the space of three days, but all the children of Israel had light where they dwelled. Then Pharao called for Moses and said: go and serve the LORD, only let your sheep, and your oxen abide, but let your children go with you. And Moses answered: thou must give us also offerings and burnt offerings for to sacrifice unto the LORD our God. Our cattle therefore shall go with us, and there shall not one hoof be left behind, for thereof must we take to serve the LORD our God. Moreover we can not know wherewith we shall serve the LORD, until we come thither. But the LORD hardened Pharao's heart, so that he would not let them go. And Pharao said unto him: get thee from me and take heed to thyself that thou see my face no more. For whensoever thou comest in my sight, thou shalt die. And Moses said: Let it be as thou hast said: I will see thy face no more. Chapter .xi.
