Bamidbar 21:6-8

Orthodox Jewish Bible

⁶ And Hashem sent fiery nechashim among the people, and they bit the people; and Am rav miYisroel died.

⁷ Therefore HaAm came to Moshe, and said, We have sinned, for we have spoken against Hashem, and against thee; pray unto Hashem that He take away the Nachash from us. And Moshe davened for the people.

⁸ And Hashem said unto Moshe, Make thee a fiery serpent, set it upon a pole; and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.
