Exodus 9:8-17

8Then the Lord said to Moses and Aaron, “Take for yourselves handfuls of soot from a kiln, and let Moses throw it toward the sky in the sight of Pharaoh. 9It will become fine dust over all the land of Egypt, and will become 1boils breaking out with sores on man and beast through all the land of Egypt.” 10So they took soot from a kiln, and stood before Pharaoh; and Moses threw it toward the sky, and it became boils breaking out with sores on man and beast. 112The 3magicians could not stand before Moses because of the boils, for the boils were on the magicians 4as well as on all the Egyptians. 12And 5the Lord 6hardened Pharaoh’s heart, and he did not listen to them, just as the Lord had spoken to Moses.

13Then the Lord said to Moses, “7Rise up early in the morning and stand before Pharaoh and say to him, ‘Thus says the Lord, the God of the Hebrews, “8Let My people go, that they may serve Me. 14For this time I will send all My plagues 9on you and your servants and your people, so that 10you may know that there is no one like Me in all the earth. 15For if by now I had put forth My hand and struck you and your people with pestilence, you would then have been cut off from the earth. 16But, indeed, 11for this reason I have allowed you to 12remain, in order to show you My power and in order to proclaim My name through all the earth. 17Still you exalt yourself against My people 13by not letting them go.
