Numbers 21:7 WBT

⁵  And the people spoke against God, and against Moses, Why have ye brought us out of Egypt to die in the wilderness? for [there is] no bread, neither [is there any] water; and our soul lotheth this light bread.

⁶  And the LORD sent fiery serpents among the people, and they bit the people; and many 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 to the LORD, that he take away the serpents from us. And Moses prayed for the people.

⁸  And the LORD said to 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.
