10 So they took furnace soot and stood before Pharaoh. Moses threw it toward heaven, and it became festering boils on man and beast.
11 The magicians could not stand before Moses because of the boils, for the boils were on the magicians as well as on all the Egyptians.
12 But the Lord hardened Pharaoh’s heart and he did not listen to them, as the Lord had told Moses.
13 Then the Lord said to Moses, “Get up early in the morning and present yourself to Pharaoh. Tell him: This is what Yahweh, the God of the Hebrews says: Let My people go, so that they may worship Me.
14 Otherwise, I am going to send all My plagues against you, your officials, and your people. Then you will know there is no one like Me in all the earth.
15 By now I could have stretched out My hand and struck you and your people with a plague, and you would have been obliterated from the earth.
16 However, I have let you live for this purpose: to show you My power and to make My name known in all the earth.
