Pride and Arrogance
Rashi explains that komemiyut means ‘to stand erect’. ,2 This definition is not easily justified with other sources: The Talmud notes that to stand with koma z’kufa, a fully erect posture, is a sign of arrogance.
Our Rabbis taught: Six things are unbecoming for a scholar. … Some add that he should not take long strides nor carry himself with a fully erect posture … since a Master has said: If one walks with upright posture even for four cubits, it is as if he pushed against the heels of the Divine Presence, since it is written, ‘The whole earth is full of His glory.’ Talmud Bavli Berachot 43b
