Numbers 21:7-9

Revised Standard Version

⁷ And the people came to Moses, and said, “We have sinned, for we have spoken against the Lord and against you; pray to the Lord, that he take away the serpents from us.” So Moses prayed for the people. ⁸ And the Lord said to Moses, “Make a fiery serpent, and set it on a pole; and every one who is bitten, when he sees it, shall live.” ⁹ So Moses made a bronze serpent, and set it on a pole; and if a serpent bit any man, he would look at the bronze serpent and live.
