Moses lifted up a serpent on a pole, and the people had to look at it to live. This is a symbol of Christ becoming sin for us on the cross.
John 3:14-15
“And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believeth in him should not perish, but have eternal life."
