קבלה אויף חבקוק 2:4

Answer. Know that all that you see an all that is perceived in the thoughts of the mind is limited. And everything that is limited has an end, and everything that has an end is unworthy. If so, then what is limitless is called Infinite and this means that it is completely unified, perfected, and changeless. And if the Infinite has no limit, then there's nothing outside of it. And therefore God is elevated, and elevates them (the S'firot) - this is the essence of everything that is hidden and revealed. And what is hidden is both the root of faith and the root of rebellion, and about this its said, "...the righteous shall live by his faith." (Habakkuk 2:4) And the sages of study agree with the words of the one who says that none surpass us because none are on this path. And the things which are emanated from the Infinite - these are the 10 S'firot.

The intention is rather [to indicate] that Habakkuk the prophet is “one who removes himself from the affairs of the world.” Those [of his] prophecies which dealt with the affairs of the world were written prior to this prophecy. [Thus] the matter of the righteous to whom evil befalls and the wicked to whom good befalls was difficult for him.⁹Cf. Hab. 1:4. Thus also [he dealt with] the mores of this world, which are the portions of the Torah that deal with worldly concerns.¹⁰Hab. 2:4 ff. After all this, the prophet left these concerns and spoke of matters concerning [the Account of] the Chariot. (Thus he] said, God is coming from Teman…it is a brilliant light (Hab. 3:3-4).

Similarly, our sages, of blessed memory, stated,⁶³⁶See Rashi and the other commentators to Proverbs 28:20; Shemot Rabba 51:1; Zohar I 199b; Reishit Chochmah, Masa uMatan b’Emunah Ch. 2; Also see Mechilta d’Rabbi Yishmael 15:26; Ramban to Exodus 15:26; Sefer Chassidim 1062, and elsewhere. “The verse,⁶³⁷Proverbs 28:20 ‘A man of integrity will increase blessings,’ refers to one who conducts his business in good faith. Such a person’s possessions will be increased, and the Holy One, blessed is He, will arrange his financial sustenance.” Moreover, such a person is called a righteous Tzaddik,⁶³⁸Reishit Chochmah, Masa uMatan b’Emunah, Ch. 2 ibid. as it states,⁶³⁹Habakkuk 2:4 “The righteous (Tzaddik) shall live by his faith.” Our sages, of blessed memory, stated,⁶⁴⁰Talmud Bavli, Makkot 24a “There are six-hundred and thirteen commandments, but Chabakkuk came and established them upon one, as it states,⁶⁴¹Habakkuk 2:4 ibid. ‘The righteous (Tzaddik) shall live by his faith.’”
