Numbers 21:2-9

2Then the people of Israel made this vow to the Lord: “If you will hand these people over to us, we will completely destroy all their towns.”

3The Lord heard the Israelites’ request and gave them victory over the Canaanites. The Israelites completely destroyed them and their towns, and the place has been called Hormah ever since.

4Then the people of Israel set out from Mount Hor, taking the road to the Red Sea to go around the land of Edom. But the people grew impatient with the long journey,

5and they began to speak against God and Moses. “Why have you brought us out of Egypt to die here in the wilderness?” they complained. “There is nothing to eat here and nothing to drink. And we hate this horrible manna!”

6So the Lord sent poisonous snakes among the people, and many were bitten and died.

7Then the people came to Moses and cried out, “We have sinned by speaking against the Lord and against you. Pray that the Lord will take away the snakes.” So Moses prayed for the people.

8Then the Lord told him, “Make a replica of a poisonous snake and attach it to a pole. All who are bitten will live if they simply look at it!”

9So Moses made a snake out of bronze and attached it to a pole. Then anyone who was bitten by a snake could look at the bronze snake and be healed!
