Exodus 9:10-12

English Standard Version

¹⁰ So they took soot from the kiln and stood before Pharaoh. And Moses threw it in the air, and it became boils breaking out in sores on man and beast. ¹¹ And ^(A)the magicians could not stand before Moses because of the boils, for the boils came upon the magicians and upon all the Egyptians. ^12 (B)But the Lord hardened the heart of Pharaoh, and he did not listen to them, as ^(C)the Lord had spoken to Moses.
