Numbers 21:7-9
The people came to Moses and said, "We sinned when
we spoke against the LORD and against you. Pray that the LORD will take
the snakes away from us." So Moses prayed for the people.
The
LORD said to Moses, "Make a snake and put it up on a pole; anyone who is
bitten can look at it and live." So Moses made a bronze snake and put
it up on a pole. Then when anyone was bitten by a snake and looked at
the bronze snake, they lived.
