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.
(Numbers 21:9 -- NIV)

Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, ¹⁵ that everyone who believes may have eternal life in him.
(John 3:14-15 -- NIV)
