1. Talmud - Mas. Rosh HaShana 29a MISHNAH. [IT IS WRITTEN] AND IT CAME TO PASS, WHEN MOSES HELD UP HIS HAND THAT ISRAEL PREVAILED, ETC. NOW DID THE HANDS OF MOSES WAGE WAR OR CRUSH THE ENEMY? NOT SO; ONLY THE TEXT SIGNIFIES THAT SO LONG AS ISRAEL TURNED THEIR THOUGHTS ABOVE AND SUBJECTED THEIR HEARTS TO THEIR FATHER IN HEAVEN THEY PREVAILED, BUT OTHERWISE THEY FELL. THE SAME LESSON MAY BE TAUGHT THUS. [IT IS WRITTEN], MAKE THEE A FIERY SERPENT AND SET IT UP ON A POLE, AND IT SHALL COME TO PASS THAT EVERYONE THAT IS BITTEN, WHEN HE SEETH IT, SHALL LIVE. NOW DID THE SERPENT KILL OR DID THE SERPENT KEEP A LIVE? NO; [WHAT IT INDICATES IS THAT] WHEN ISRAEL TURNED THEIR THOUGHTS ABOVE AND SUBJECTED THEIR HEARTS TO THEIR FATHER IN HEAVEN, THEY WERE HEALED, BUT OTHERWISE THEY PINED AWAY.
