9:13. And the Lord said to Moses: Arise in the morning, and stand before Pharao, and thou shalt say to him: Thus saith the Lord, the God of the Hebrews: Let my people go to sacrifice to me.
9:14. For I will at this time send all my plagues upon thy heart, and upon thy servants, and upon thy people; that thou mayst know that there is none like me in all the earth.
9:15. For now I will stretch out my hand to strike thee, and thy people, with pestilence, and thou shalt perish from the earth.
9:16. And therefore have I raised thee, that I may shew my power in thee, and my name may be spoken of throughout all the earth.
9:17. Dost thou yet hold back my people; and wilt thou not let them go?
9:18: Behold I will cause it to rain to morrow at this same hour, an exceeding great hail; such as hath not been in Egypt from the day that it was founded, until this present time.
9:19. Send therefore now presently, and gather together thy cattle, and all that thou hast in the field; for men and beasts, and all things that shall be found abroad, and not gathered together out of the fields which the hail shall fall upon, shall die.
9:20. He that feared the word of the Lord among Pharao's servants, made his servants and his cattle flee into houses:
9:21. But he that regarded not the word of the Lord, left his servants, and his cattle in the fields.

9:23. And Moses stretched forth his rod towards heaven, and the Lord sent thunder and hail, and lightnings running along the ground: and the Lord rained hail upon the land of Egypt.
9:24. And the hail and fire mixt with it drove on together: and it was of so great bigness, as never before was seen in the whole land of Egypt since that nation was founded.
9:25. And the hail destroyed through all the land of Egypt all things that were in the fields, both man and beast: and the hail smote every herb of the field, and it broke every tree of the country.
9:26. Only in the land of Gessen, where the children of Israel were, the hail fell not.
9:27. And Pharao sent and called Moses and Aaron, saying to them: I have sinned this time also, the Lord is just: I and my people, are wicked.
9:28. Pray ye to the Lord that the thunderings of God and the hail may cease: that I may let you go, and that ye may stay here no longer.
9:29. Moses said: As soon as I am gone out of the city, I will stretch forth my hands to the Lord, and the thunders shall cease, and the hail shall be no more: that thou mayst know that the earth is the Lord's:

Exodus Chapter 10
The eighth plague of the locusts. The ninth, of darkness: Pharao is still hardened.
10:1. And the Lord said to Moses: Go in to Pharao; for I have hardened his heart, and the heart of his servants: that I may work these my signs in him,
10:2. And thou mayst tell in the ears of thy sons, and of thy grandsons, how often I have plagued the Egyptians, and wrought my signs amongst them: and you may know that I am the Lord.
10:3. Therefore Moses and Aaron went in to Pharao, and said to him: Thus saith the Lord God of the Hebrews: How long refusest thou to submit to me? let my people go, to sacrifice to me.
10:4. But if thou resist, and wilt not let them go, behold I will bring in to-morrow the locusts into thy coasts;
10:5. To cover the face of the earth, that nothing thereof may appear, but that which the hail hath left may be eaten: for they shall feed upon all the trees that spring in the fields.
10:6. And they shall fill thy houses, and the houses of thy servants, and of all the Egyptians: such a number as thy fathers have not seen, nor thy grandfathers, from the time they were first upon the earth, until this present day. And he turned himself away, and went forth from Pharao.

10:8. And they called back Moses, and Aaron, to Pharao; and he said to them: Go, sacrifice to the Lord your God: who are they that shall go?
10:9. Moses said: We will go with our young and old, with our sons and daughters, with our sheep and herds: for it is the solemnity of the Lord our God.
10:10. And Pharao answered: So be the Lord with you, as I shall let you and your children go: who can doubt but that you intend some great evil?
10:11. It shall not be so, but go ye men only, and sacrifice to the Lord: for this yourselves also desired. And immediately they were cast out from Pharao's presence.
10:12. And the Lord said to Moses: Stretch forth thy hand upon the land of Egypt unto the locust, that it come upon it, and devour every herb that is left after the hail.
10:13. And Moses stretched forth his rod upon the land of Egypt: and the Lord brought a burning wind all that day, and night; and when it was morning, the burning wind raised the locusts.
10:14. And they came up over the whole land of Egypt; and rested in all the coasts of the Egyptians, innumerable, the like as had not been before that time, nor shall be hereafter.
10:15. And they covered the whole face of the earth, wasting all things.
And the grass of the earth was devoured, and what fruits soever were on the trees, which the hail had left; and there remained not any thing that was green on the trees, or in the herbs of the earth, in all Egypt.
10:16. Wherefore Pharao in haste called Moses and Aaron, and said to them: I have sinned against the Lord your God, and against you.
10:17. But now forgive me my sin this time also, and pray to the Lord your God, that he take away from me this death.
10:18: And Moses going forth from the presence of Pharao, prayed to the Lord:
10:19. 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.
10:20. And the Lord hardened Pharao's heart, neither did he let the children of Israel go.
10:21. And the Lord said to Moses: Stretch out thy hand towards heaven: and may there be darkness upon the land of Egypt so thick that it may be felt.
Darkness upon the land of Egypt, so thick that it may be felt... By means of the gross exhalations, which were to cause and accompany the darkness.
10:22. And Moses stretched forth his hand towards heaven: and there came horrible darkness in all the land of Egypt for three days.
10:23. No man saw his brother, nor moved himself out of the place where he was: but wheresoever the children of Israel dwelt, there was light.
