And Hashem said to Moshe: Make for yourself a fiery serpent and set it upon a pole, and it shall be that everyone who is bitten and looks at it shall live.
English: Does a serpent kill or a serpent heal? Rather, when Yisrael look upward and subject their hearts to their Father in Heaven they are healed; if not, they waste away.
