And Moses made a serpent of brass, and set it upon the standard: and it came to pass, that if a serpent had bitten any man, when he looked unto the serpent of brass, he lived.

And Moses maketh a serpent of brass, and setteth it on the ensign, and it hath been, if the serpent hath bitten any man, and he hath looked expectingly unto the serpent of brass -- he hath 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.
