Numbers 21:7-9

7So the people came to Moses and they said, ‘We did a bad thing when we spoke against the Lord and against you. Please pray to the Lord on our behalf. Ask him to remove the snakes from us.’ So Moses prayed for the people.

8The Lord said to Moses, ‘Make a model of a snake and put it up high on a pole. When a snake bites anyone, they must look at the bronze snake. Then they will not die.’

9Moses made a bronze snake and he put it on a pole. When a snake bit anyone and they looked at the bronze snake, they did not die.
