Numbers 21:7-9 And the people came to Moses and said, We have sinned, for we have spoken against the Lord, and against thee: pray therefore to the Lord, and let him take away the serpent from us.

Brenton⁽ⁱ⁾ ⁷ And the people came to Moses and said, We have sinned, for we have spoken against the Lord, and against thee: pray therefore to the Lord, and let him take away the serpent from us. ⁸ And Moses prayed to the Lord for the people; and the Lord said to Moses, Make thee a serpent, and put it on a signal-staff; and it shall come to pass that whenever a serpent shall bite a man, every one so bitten that looks upon it shall live. ⁹ And Moses made a serpent of brass, and put it upon a signal-staff: and it came to pass that whenever a serpent bit a man, and he looked on the brazen serpent, he lived.
