The Lord said to Moses, "Go to Pharaoh and say to him, 'Thus says the Lord, the God of the Hebrews: Let My people go to worship Me. For if you refuse to let them go, and continue to hold them, then the hand of the Lord will strike your livestock in the fields--the horses, the asses, the camels, the cattle, and the sheep--with a very severe pestilence. But the Lord will make a distinction between the livestock of Israel and the livestock of the Egyptians, so that nothing shall die of all that belongs to the Israelites. The Lord has fixed the time: tomorrow the Lord will do this thing in the land.'" And the Lord did so the next day: all the livestock of the Egyptians died, but of the livestock of the Israelites not a beast died. When Pharaoh inquired, he found that not a head of the livestock of Israel had died; yet Pharaoh remained stubborn, and he would not let the people go.
Then the Lord said to Moses and Aaron, "Each of you take handfuls of soot from the kiln, and let Moses throw it toward the sky in the sight of Pharaoh. It shall become a fine dust all over the land of Egypt, and cause an inflammation breaking out in boils on man and beast throughout the land of Egypt." So they took soot of the kiln and appeared before Pharaoh; Moses threw it toward the sky, and it caused an inflammation breaking out in boils on man and beast. The magicians were unable to confront Moses because of the inflammation, for the inflammation afflicted the magicians as well as all the other Egyptians. But the Lord stiffened the heart of Pharaoh, and he would not heed them, just as the Lord had told Moses.
The Lord said to Moses, "Early in the morning present yourself to Pharaoh and say to him, 'Thus says the Lord, the God of the Hebrews: Let My people go to worship Me. For this time I will send all My plagues upon your person, and your courtiers, and your people, in order that you may know that there is none like Me in all the world.
You shall present an offering by fire, a burnt offering, to the Lord: two bulls of the herd, one ram, and seven yearling lambs--see that they are without blemish. The meal offering with them shall be of choice flour with oil mixed in: prepare three-tenths of a measure for a bull, two-tenths for a ram; and for each of the seven lambs prepare one-tenth of a measure. And there shall be one goat for a sin offering, to make expiation in your behalf. You shall present these in addition to the morning portion of the regular burnt offering. You shall offer the like daily for seven days as food, an offering by fire of pleasing odor to the Lord; they shall be offered, with their libations, in addition to the regular burnt offering. And the seventh day shall be a sacred occasion for you: you shall not work at your occupations.
