(Old Testament)-Aaron's staff struck the dust on the ground and turned it into lice all over Egypt. The sorcerer also tried to produce lice by witchcraft, but he couldn't, so people and livestock had lice. Egyptians worship the earth as the mother of the gods, but God will perform miracles on the earth, strike dust and grow lice everywhere, so that clean Egyptians will be more unbearable because of the plague of lice. The magician said to Pharaoh, "This is God's means", which means "This is God's finger". Obviously, they admit that what they do is only out of their own magic and can't compete with the power of God. This just means that God gave Pharaoh a little warning with his tiny authority (8: 19); But in the end, once God's greater authority and ability are displayed (15: 6, 12, 16), his greatest retribution will come to him.
