Musar sobre Provérbios 19:19

Those who subdue their souls' anger and prevail upon their nature to restrain it, have been described as noble and characterized as exalted. Thus the sage said (Prov. xvi. 32), "He that is slow to anger is better than the mighty." This is one of the thirteen attributes ascribed to God, exalted is He, in the passage (Ex. xxxiv. 6), "And the Lord passed by before him," etc. It is said that as scab is a disease of the body, so is wrath a disease of the soul. The moral man must not become wrathful often, because, by reason of his wrath, he is compelled to bear burdens. Thus saith the sage (Prov. xix. 19), "A man of great wrath shall bear punishment."
