Mussar: A Jewish Psycho-Ethical Model for Our Time
God sent the fiery serpents against the people and they bit the people….God said to Moses: “Make yourself a fiery serpent and place it on a pole, and it will be that anyone who was bitten will look at it and live.” Moses made a serpent of copper and placed it on the pole; so that if the serpent bit a man, he would stare at the copper serpent and live. (Bemidbar21:4–10)
