Bet (or Feh) is the seventeenth letter of the Hebrew Alphabet. It signifies the number eighty. Peh means “mouth” and is related to the letter Hei (“throat”). Because of this, Peh/ Feh refers to the power of speech in Kabbalah. This power is a double-edged sword. As it says in “Death and life are in the power of the tongue” (Proverbs 18:21).
Speech is a spiritual power that can cause good or evil, depending on how it is used. Words from a blessing can heal, while violent actions can be birthed from violent words. From Peh/Feh we learn that to control our tongues can lead to selfmastery. The shape of the Peh/Feh represents the spiritual spark that is the soul, created inside the physical body when one is born again.
