זוהר שמות — דף עה ע”א

Parasha Yitro, folio 75a — The Zohar continues the teaching on kabbalistic physiognomy and standing prayer. The Matronita rises for those who stand upright, called legs. Israel left as servants and Moses called them sons of the Holy One. Kabbalistic physiognomy teaches to read the signs in hair, forehead, face and hands. Blessed are the companions from whom no secret is hidden, and Rabbi Shimon blesses them with promises of higher worlds.
