The first Gate of the Sepher Yetzirah. It has a value of three. There is an opposition in the meanings of the letters A, or the Hebrew aleph meaning ox and the B, or the Hebrew Bet meaning house as well as their respective Tarot correspondences of The Fool and The Magician. AB has the meanings of father, master, source, and ancestor. Astrologically this Gate corresponds to Air and Mercury, which brings to mind the elasticity of the god Mercury; however this is before he is sent on a mission (as the messenger of the gods), as when he is about to work then his nature is of Water.
