Bemiḏbar (Numbers) 21:5-8

And the people spoke against Elohim and against Mosheh, “Why have you brought us up out of Mitsrayim to die in the wilderness? For there is no food and no water, and our being loathes this light bread.” And יהוה sent fiery serpents among the people, and they bit the people. And many of the people of Yisra’ĕl died. Then the people came to Mosheh, and said, “We have sinned, for we have spoken against יהוה and against you. Pray to יהוה to take away the serpents from us.” So Mosheh prayed on behalf of the people. And יהוה said to Mosheh, “Make a fiery serpent, and set it on a pole. And it shall be that everyone who is bitten, when he looks at it, shall live.”
