Exodus 9:12

¹⁰So he took of the ashes of the furnace before Pharaoh, and Moses scattered it toward heaven, and it became sore blains breaking forth both on men and on beasts.

¹¹And the sorcerers could not stand before Moses because of the sores, for the sores were on the sorcerers, and in all the land of Egypt.

— Exodus 9:12 —

¹³And the Lord said to Moses, Rise up early in the morning, and stand before Pharaoh; and thou shalt say to him, These things saith the Lord God of the Hebrews, Send away my people that they may serve me.

¹⁴For at this present time do I send forth all my plagues into thy heart, and the heart of thy servants and of thy people; that thou mayest know that there is not another such as I in all the earth.
