What does the Bible say about the brazen serpent in Numbers?

The brazen serpent, as described in the Book of Numbers, served as a powerful symbol of God's provision for physical and spiritual healing. When the Israelites were afflicted by poisonous serpents due to their sin, God instructed Moses to create a serpent of bronze and lift it on a pole. Those who looked upon it, in faith, were healed. This mirrors the salvific work of Christ, who was lifted up on the cross so that whosoever believes in Him may have eternal life (John 3:14-15). The lifting of the serpent was God's ordained solution, reflecting His sovereignty and mercy in addressing their plight and foreshadowing Christ's ultimate sacrifice for our sins.
