So Moses made a bronze serpent, and put it on a pole; and so it was, if a serpent had bitten anyone, when he looked at the bronze serpent, he lived.—Numbers 21:9
Moses was divinely commanded to make a serpent of brass resembling the living ones, and to elevate it among the people. To this, all who had been bitten were to look, and they would find relief. He did so, and the joyful news was sounded throughout the encampment that all who had been bitten might look upon the brazen serpent and live. Many had already died, and when Moses raised the serpent upon the pole, some would not believe that merely gazing upon that metallic image would heal them; these perished in their unbelief. Yet there were many who had faith in the provision which God had made. Fathers, mothers, brothers, and sisters were anxiously engaged in helping their suffering, dying friends to fix their languid eyes upon the serpent. If these, though faint and dying, could only once look, they were perfectly restored.
The people well knew that there was no power in the serpent of brass to cause such a change in those who looked upon it. The healing virtue was from God alone. In His wisdom He chose this way of displaying His power. By this simple means the people were made to realize that this affliction had been brought upon them by their sins. They were also assured that while obeying God they had no reason to fear, for He would preserve them.
The lifting up of the brazen serpent was to teach Israel an important lesson. They could not save themselves from the fatal effect of the poison in their wounds. God alone was able to heal them. Yet they were required to show their faith in the provision which He had made. They must look in order to live. It was their faith that was acceptable with God, and by looking upon the serpent their faith was shown. They knew that there was no virtue in the serpent itself, but it was a symbol of Christ; and the necessity of faith in His merits was thus presented to their minds. Heretofore many had brought their offerings to God, and had felt that in so doing they made ample atonement for their sins. They did not rely upon the Redeemer to come, of whom these offerings were only a type. The Lord would now teach them that their sacrifices, in themselves, had no more power or virtue than the serpent of brass, but were, like that, to lead their minds to Christ, the great sin offering.—Patriarchs and Prophets, 430.
Further Reflection: Has God ever hidden a blessing for me in a seemingly odd command?
