"When Pharaoh saw that there was respite, he hardened his heart." At the command of God, Aaron stretched out his hand, and the dust of the earth became lice throughout all the land of Egypt. Pharaoh called upon the magicians to do the same, but they could not. The work of God was thus shown to be superior to that of Satan. The magicians themselves acknowledged, "This is the finger of God." But the king was still unmoved.

Da Farao så, at han havde fået luft, forhærdede han sit hjerte. På Guds befaling rakte Aron sin hånd ud, og jordens støv blev til myg i hele Ægyptens land. Farao forlangte at troldmændene skulle gøre det samme, men de kunne ikke. Guds værk viste sig derved at være Satans overlegent. Selv troldmændene erkendte: Det er Guds finger! Men kongen var stadig urokkelig.
