Numbers 21:2-12
English Standard Version
Chapter 21
2And Israel vowed a vow to the Lord and said, "If you will indeed give this people into my hand, then I will devote their cities to destruction." 3And the Lord heeded the voice of Israel and gave over the Canaanites, and they devoted them and their cities to destruction. So the name of the place was called Hormah.
4From Mount Hor they set out by the way to the Red Sea, to go around the land of Edom. And the people became impatient on the way.
5And the people spoke against God and against Moses, "Why have you brought us up out of Egypt to die in the wilderness? For there is no food and no water, and we loathe this worthless food."
6Then the Lord sent fiery serpents among the people, and they bit the people, so that many people of Israel died.
7And the people came to Moses and said, "We have sinned, for we have spoken against the Lord and against you. Pray to the Lord, that he take away the serpents from us." So Moses prayed for the people.
8And the Lord said to Moses, "Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live."
9So Moses made a bronze serpent and set it on a pole. And if a serpent bit anyone, he would look at the bronze serpent and live.
