What does Exodus 7:12 mean?
Scripture does not specify how many Egyptian magicians were involved in this event (Exodus 7:10–11). Tradition associates the names Jannes and Jambres with Pharaoh's sorcerers (2 Timothy 3:8). Either by supernatural power granted by evil spirits, or through trickery, they have produced snakes from their own staves. This is enough to convince Pharaoh to ignore demands coming from Moses and Aaron. However, the serpent formed from Aaron's staff swallows the snakes made from the Egyptians' staves. Even if Pharaoh thought his sorcerers had real power, this should have been seen as a sign of God's supremacy.Snakes are usually associated with evil or judgment (Genesis 3:1; 49:17; Revelation 12:9). In this context, the importance is in the Egyptian understanding of these images. Serpents were also among the religious symbols of ancient Egypt. Pharaohs wore images of cobras on their heads as symbols of their authority to rule. When the snakes of Egypt are swallowed, it shows that the power being demonstrated by the Lord will overwhelm and undo Pharaoh's power to rule over Israel (Exodus 3:19–20; 12:41).
