Numbers 21:8

6 And the LORD sent fiery serpents among the people, and they bit the people; and much people of Israel died.

7 Therefore the people came to Moses, and said, We have sinned, for we have spoken against the LORD, and against thee; pray unto the LORD, that he take away the serpents from us. And Moses prayed for the people.

And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.

9 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.

10 And the children of Israel set forward, and pitched in Oboth.

Do read the surrounding verses too, because the context often says more than a single verse.
