And The Lord said to Moses, after He saw that Pharaoh's heart was hardened, that Moses must take Pharaoh to the water the next morning. He must then say to to Pharaoh: 'The Lord God of the Hebrews had sent me unto thee, and He said to thee to let His people go, so that they can serve Him in the wilderness; but thee wouldn't hear.'
First Plague: Water Turn Into Blood
And The Lord spoke unto Moses: 'Say to Aaron, 'Take thy rod, and stretch out thy hand upon all the waters of Egypt, that they may become blood, and that there may be blood throughout Egypt, both in vessels of wood, and in vessels of stone.'
And Moses and Aaron did as God commanded, and all the waters in Egypt turned into blood, and everything happened as The Lord had said.
But the magicians of Pharaoh also did so with their enchantments, and Pharaoh's heart was hardened, and he didn't listen to God's message. The Egyptians digged around the river for drinkable water, and the plague went on for seven days.
Second Plague: Frogs
And The Lord then said to Moses to warn Pharaoh that if he doesn't let the Hebrews go to serve Him, that God would smite Egypt's borders with frogs ... 'And the river shall bring forth frogs abundantly, which shall go up and come into thy house, thy bed chamber, upon thy bed, into the house of thy servants, upon thy people, into thy ovens, and into thy kneading troughs.'
And The Lord spoke unto Moses: 'Say to Aaron, 'Take thy rod, and stretch out thy hand upon all the waters of Egypt, and cause the frogs to come up upon the land of Egypt.' Aaron did so, and the frogs came up and covered the land of Egypt. But the magicians of Pharaoh also did so with their enchantments.
Pharaoh called Moses and Aaron and told them that if God take the frogs away, he would let the Israelites go so that they may sacrifice unto The Lord. Moses and Aaron then went out from Pharaoh, and Moses cried unto The Lord because of the frogs that He had brought against Pharaoh. And the Lord did according to the word of Moses, and all the frogs died in the houses, the villages and the fields, except in the river. The Egyptians gathered them together in heaps, and the land stank. But when Pharaoh saw that there was respite, he hardened his heart, and went back on his word.
Third Plague: Lice
And The Lord spoke unto Moses: 'Say unto Aaron, 'Take thy rod, and stretch out thy hand and smite the dust of the land, that it may become lice throughout all the land of Egypt.'
And they did so, and the dust of the earth became lice in man, and in beast. And the magicians tried to bring forth lice, but they could not. They then said unto Pharaoh: 'This is the finger of God.'
But Pharaoh's heart was hardened and he wouldn't listen, after God took the lice away.
Fourth Plague: Flies
And The Lord said to Moses: 'Rise up early in the morning, and stand before Pharaoh, and say unto him, 'Thus saith The Lord ... Let My people go, that they may serve me. Else, behold, I will send swarms of flies upon thee and the whole of Egypt, but not in the land of Goshen where My people dwell.'
And The Lord did so, and the land was corrupted by the reason of the swarms of flies. And Pharaoh called for Moses and Aaron and said to them: 'Go ye, sacrifice to your God in the land.'
Moses and Aaron then went out from Pharaoh, and Moses cried unto The Lord because of the flies that He had brought against Pharaoh. And the Lord did according to the word of Moses, but when the flies was gone, Pharaoh hardened his heart again and went back on his word.
Fifth Plague: Pestilence
Then The Lord said unto Moses: 'Rise up early in the morning, and stand before Pharaoh, and say unto him: 'So saith The Lord ... Let my people go, that they may serve Me. For I will at this time send all my plagues upon thy heart, and upon thy servants, and upon thy people; that thou mayest know that there is none like Me in all the earth. For now I will stretch out My hand, that I may smite thee and thy people with pestilence, and thou shall be cut of the earth.' There was great death in the land of Egypt. But the heart of Pharaoh was hardened once again.
Sixth Plague: Boils
And The Lord said unto Moses and unto Aaron: 'Take to you handfuls of ashes of the furnace, and let Moses sprinkle it toward the heaven in the sight of Pharaoh.
And it shall become small dust in all the land of Egypt., and shall be a boil breaking forth with blains upon man, and upon beast, throughout all the land of Egypt.
They did as The Lord commanded, and it became as The Lord said. And the magicians could not stand before Moses, for the boils was upon the magicians as well. Man and beast suffered greatly. And The Lord hardened the heart of Pharaoh.
Seventh Plague: Hail And Fire
And The Lord told Moses to stretch forth his hand toward heaven, that there may be hail in all the land of Egypt.
And Moses did so, and the Lord sent thunder and hail, and the fire ran along upon the ground, and fire mingled with the hail.
And the hail destroyed everything in it's path ... man, beast and plant. Except for Goshen where the Israelites lived.
Pharaoh promised again to let the Israelites go, but as soon as the skies cleared up, he hardened his heart.
Eigth Plague: Locusts
The Lord sent the plague of locusts ... so much locusts that the earth was not visible, and they ate everything in their path.
Again Pharaoh promised to let the Israelites go, and again he sinned and hardened his heart, as soon as the locusts was gone.
Nineth Plague: Darkness
Then The Lord hit the land of Egypt with darkness. It was a thick darkness that made everything invisible. It went on for three days.
Again Pharaoh promised to let the Israelites go, and again he sinned and hardened his heart, as soon as the darkness was gone.
The Lord finally had enough of Pharaoh.
Tenth Plague: Death Of The Firstborn
And Moses said to the people: 'Thus sayeth The Lord, 'When the time comes, about midnight will I go out into the midst of Egypt, and all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh unto the firstborn of the maid servant, and all the firstborn of the beasts, but not again the children of Israel.'
He furthermore instructed Moses that every house of Israel [12] must slay a year old male lamb without blemish ... on the fourteenth day ... take the blood and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it. They must eat it in the night, roasted with fire, and unleavened bread; and with bitter herbs, but the meat must not be raw.
The Lord also said to Moses: 'And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste ... it is the Lord's passover. For I will pass through the land of Egypt that night, and will smite all the firstborn, both man and beast; and against all the gods of Egypt I will execute judgment: I am The Lord. When I see the blood upon the houses, I will pass over you, and the plague shall not be upon you.
And it came to pass, that at midnight The Lord smote all of the firstborn, of man and beast, in the land of Egypt ... and there was a great cry in Egypt. But the firstborn of Israel were spared.
