Tet (or Ṭeth or Teith) is the ninth letter of the Hebrew Alphabet. It signifies the number nine (the number of man), or 9,000 if followed by an apostrophe. Teth literally means “basket” or “nest.” It is the symbol of the good in God’s creation.
Dealing with purity and impurity, Tet teaches us to choose the light. More than this, it also helps us see the hidden good to be found when what we perceive to be “bad things” happen.
Tet’s essence is feminine; representing femininity and pregnancy, as full-term pregnancy requires nine months. It reminds us of Chesed, the kindness and mercy in God’s creation (1 Nephi 3:40-41, 46-64 RAV,11:3-4, 8-22 OPV). Everything is eternal, thanks to Christ’s atonement nothing has to be lost.
Thus, Tet is both the fruit of the tree of the knowledge of Good and Evil, and it is the fruit of the Tree of Life. By knowing good from evil we may separate the light from the darkness. By choosing the light, Christ cleans and purifies us, erasing bad deeds that were caused by our slavery to Ego. Tet allows for teshuvah.
