Musar su Isaia 10:33

Our Rabbis said: "Every man who is impudent or proud of spirit it is as though he were an idolator" (Sotah 4b), for it is written, "Every one that is proud in heart is an abomination to the Lord" (Prov. 16:5) and it is written there: "You must not bring an abhorrent thing (idol) into your house …" (Deut. 7:26). And there are those who say it is as though he violated all the laws against sexual license, for it is written: "For all these abominations were done by the people who were in the land before you and the land became defiled …" (Lev. 18:27). And there are those who say, "It is as though he built a place for idolatry." And they said in Sotah 5a, "Every man who is arrogant of spirit becomes less in the end as it is said: 'They are exalted for a little while' (Job 24:25). And such a one is deserving to be hewn down like a grove planted for idol worship, as it is said: 'And the high ones of stature shall be hewn down' (Is. 10:33). And his dust shall not awaken and the Spirit of God laments over him. The Holy One Blessed be He, said, 'I and he cannot live in the same world,' as it is said: 'Whoso is haughty of eye and proud of heart, him will I not suffer'" (Ps. 101:5).

We read in the Sefer Habahir, that the reason the Torah commands circumcision to be performed on the eighth day of the infant's life is that man possesses eight extremities, i.e. his right and left hand, the right and left foot, the head, the body, the male member and its mate, since the Torah describes man as "ודבק אשתו והיו לבשר אחד, "he cleaves to his wife so that they become one flesh” (Genesis 2,24). When G–d said to Abraham: אני הנני בריתי אתך, "I, here My covenant is with you," this is a reference to the fact that the שכינה is known as Ani, and that the heavenly covenant is symbolized on the body by a ציון, a mark. Once the male glans is uncovered, this enables the שכינה to return to ציון, Zion, and man on earth remains whole, retains the image of G–d. When that condition exists, all his 248 limbs are whole, and this is what the name 248=אברהם represents. When in that condition, Abraham is able to enter the Zion on this earth. We can then be a nation on our own land for the imprint of G–d is on our bodies. This seal signifies that we are permanently different and distinct from the other nations and are indeed part of the holiness of G–d.

One must not walk in an overly erect posture nor with excessive heaviness, heel to toe, rather as one going to his occupations. Likewise our sages, of blessed memory, said: "If one walks with an overly erect posture even for four cubits, it is as if he pushes against the feet of the Divine Presence" (Berachot 43b), and it is written: "and those of lofty height will be cut down" (Isaiah 10:33).
