Numbers 21:4-9

4Then they moved from Mount Hor, following the road that goes to the Red Sea, in order to get around Edom. The people became impatient on the trip

5and criticized God and Moses. They said, “Why did you make us leave Egypt—just to let us die in the desert? There’s no bread or water, and we can’t stand this awful food!”

6So the Lord sent poisonous snakes among the people. They bit the people, and many of the Israelites died.

7The people came to Moses and said, “We sinned when we criticized the Lord and you. Pray to the Lord so that he will take the snakes away from us.” So Moses prayed for the people.

8The Lord said to Moses, “Make a snake, and put it on a pole. Anyone who is bitten can look at it and live.”

9So Moses made a bronze snake and put it on a pole. People looked at the bronze snake after they were bitten, and they lived.
