Numbers 21:7-9

New Revised Standard Version Catholic Edition

⁷ The people came to Moses and said, “We have sinned by speaking against the Lord and against you; pray to the Lord to take away the serpents from us.” So Moses prayed for the people. ⁸ And the Lord said to Moses, “Make a poisonous^[a] serpent, and set it on a pole; and everyone who is bitten shall look at it and live.” ⁹ So Moses made a serpent of bronze, and put it upon a pole; and whenever a serpent bit someone, that person would look at the serpent of bronze and live.
