GEN449 Weapons first appeared in the Torah at the very beginning of Creation after Adam and Eve sinned, with the flaming sword that protecting the Garden of Eden and the Tree of Life, preventing man from re-entering.  This first divine weapon then, was intended to protect property, like a gun in a home, but for defensive purposes only.  A few generations later, as society developed implements and tools for working the land and musical instruments, one person, Tuval Kayin, forged sharp instruments out of bronze and iron, which Rashi says were weapons made for murders to kill people.  Genesis 4:22 with Rashi commentary.  Thus, the first human weapons were made in order to hurt individuals and kill human beings, not essentially different from the guns and other weapons that are manufactured to kill people today.  Needles s to say, the Rabbis did not look upon this invention as a positive development for mankind.  AMJV 120
