"Parle ainsi à Aaron: Quelqu’un de ta postérité, dans les âges futurs, qui serait atteint d’une infirmité, ne sera pas admis à offrir le pain de son Dieu.
Zohar
"than one who pranks himself" is as we said, that he puts on airs, curls his hair, and acts haughtily, "but lacks bread." This means a lack of faith, as it is written, "to offer the bread of his Elohim" (Vayikra 21:17), and "the bread of their Elohim they do offer" (Ibid. 6). Bread is the Shechinah in both verses. Faith is the Shechinah, so lacking bread means lacking faith.
