Nun (or Nuun) is the fourteenth letter of the Hebrew Alphabet. It signifies the number 50, and in its final form represents 700. Nun is a symbol of both faithfulness and the reward for faithfulness, new spiritual birth, coming out of the waters of Mem.
Nun stands for humility, as it is bent both above and below. It represents the soul Neshama, the heavenly spark housed in the earthly container of the body. Nuun means “fish” in Arabic, Nun can be thought of then as the fish that swims in the waters of the Torah, represented by Mem. Connected to fertility, continuity and the ability to increase and multiply, Nun brings us out of the waters of rebirth and onto growth in Grace.
Nun also represents the 50 Gates of Wisdom of Binah, indicating the constant presence and the humility of the soul. Like the letter Nun, the soul is bent as a person in prayer, humble constantly giving light but staying hidden. Thus Nun us to be bound to the will of the Creator, not our own Egoism. We must bend to God in the things spiritual (above) and worldly (below). Through Nun we better learn to be supple and flexible, like the fish, and not to be resistant to change. Nun reminds us to listing to our Neshama, through which the Creator is always present in us.
