Parallel
Numbers 21:9
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.
So Moses made a bronze snake and mounted it on a pole. If anyone who was bitten looked at the bronze snake, he would live.
