이사야 2:22의 Musar

And this is the language of the holy Zohar (Parshath Tetzaveh) on the verse (Isaiah 2:22): "Leave off from the man asher neshamah be'apo, ki bameh nechshav hu." Here, the Holy One Blessed be He has commanded a man and warned him to guard himself against those men who have inclined their ways from the way of good to the way of evil and who have defiled themselves with that uncleanliness of the sitra achara ["the other side"]. And how shall a man know how to distinguish between one he should draw near to and one he should separate from? By his anger itself he can know that man and distinguish him [from the other]. If he guards his holy soul when his anger comes upon him, not to uproot it from its place and repose in its stead a foreign god — that is the man who is worthy, etc. And if he does not guard it, but uproots this celestial holiness from its place and reposes in its place the sitra achara ["the other side"], then certainly that is the man who rebels against his Master, and it is forbidden to draw near to him or to befriend him. And this is the intent of (Iyyov 18:4): 'Toref nafsho be'apo,' viz. He tears [toref] and uproots his soul because of his anger [be'apo] and reposes within himself a foreign god. And concerning this it is written: 'Leave off from the man asher neshamah be'apo" — whose soul [he tears] in his wrath [be'apo], whose soul he exchanges in his wrath [for a foreign god], ki bameh nechshav hu. With what [bameh] is that man to be distinguished? He is to be accounted a worshipper of idolatry [bamah, an altar to idolatry (like 'bameh'), etc.]"

Rabbi Shimon ben Yochai in Sotah 4b compares an arrogant person to an idol worshiper. This exegesis is based on the Torah applying the word "abomination" to both of these types of individual. Rabbi Yehudah castigates haughtiness as being the equivalent of heresy of the first order. He quotes a verse from our portion. It is written: ורם לבבך ושכחת את ה' אלוקיך "When you become haughty you forget the Lord your G–d." Different sages in the Talmud heap more scorn on arrogant people, each one supplying scriptural proof. The common denominator for this universal condemnation of the haughty person is that, inasmuch as G–d is our Master and we are His servants, how could a servant arrogate to himself importance in the presence of his master?
