What does the Bible say about Moses' signs in Exodus 4?

In Exodus 4, Moses is given three signs by God to demonstrate His authority and to confirm His message. The first sign involves Moses' rod becoming a serpent, depicting God's power and the victory over evil, while the second sign of Moses' hand becoming leprous represents the corruption of sin and the cleansing power of Christ. These signs foreshadow the deliverance that Jesus Christ brings to sinners, showcasing God's grace and plan for redemption. Through the preaching of the gospel, these signs continue to testify to the work of Christ today.
