Numbers 21:6; Numbers 21:8; Numbers 21:9

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

8 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.
