8 And the Lord said to Moses and Aaron: Take to you handfuls of ashes out of the chimney, and let Moses sprinkle it in the air in the presence of Pharao.
9 And be there dust upon all the land of Egypt: for there shall be boils and swelling blains both in men and beasts in the whole land of Egypt.
10 And they took ashes out of the chimney, and stood before Pharao, and Moses sprinkled it in the air: and there came boils with swelling blains in men and beasts.
11 Neither could the magicians stand before Moses for the boils that were upon them, and in all the land of Egypt.
12 And the Lord hardened Pharao's heart, and he hearkened not unto them, as the Lord had spoken to Moses.
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.
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 there is none like me in all the earth.
