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.

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.
