What does the Bible say about the story of the serpent on a pole?

In Numbers 21, the Israelites faced severe consequences for their complaints against God, leading to the arrival of fiery serpents that bit many, causing death. When the people recognized their sin, they sought Moses' intercession, and God instructed Moses to create a bronze serpent and raise it on a pole. Anyone who looked at this serpent would be healed. This account highlights God's grace and mercy, as the serpent symbolizes the remedy for sin, pointing to the ultimate salvation found in Jesus Christ, who was lifted up for our sins.
