Musar su Deuteronomio 7:6

Also consider that the Holy One, Blessed be He, has given permission to no people in the world to tell His praises other than Israel, as it is said, "The people which I have formed for Myself, that they might tell of My praise" (Is. 43:21). And it is written, "For thou art a holy people unto the Lord thy God" (Deut. 7:6). And it is written, "And the Lord hath avouched thee this day to be His own treasure" (Deut. 26:18). And it is written "To make thee high above all nations" (Deut. 26:19). And the Holy One, Blessed be He, did not give any creature the ability to know the Name, Blessed be He, save to Israel, as it is written, "Unto thee it was shown, that thou mightest know that the Lord, He is God; there is none else beside Him" (Deut. 4:35). And it is written, "And what great nation is there, that hath statutes, and ordinances so righteous as all this law, which I set before you this day" (Deut. 4:8). And it is written, "Thou shalt fear the Lord thy God; and Him shalt thou serve" (Deut. 6:13).

One must learn from the example of the Holy One Blessed is He. For He is the King of the Kings of Kings, yet He chose us out of all the peoples and tongues and called us “My firstborn son Israel” (Shemos 4:22), “the treasured people” (Devarim 7:6) and “Yeshurun” [a straight and honest people] (Devarim 32:15, Yeshayahu 44:2). However, if the children of Israel ignore the will of the Omnipresent, and follow their heart’s desire to engage in commerce and worldly pleasures, what satisfaction can the blessed Creator derive from them? Moreover, even if a person prays and dons tefillin and tzitzis on occasion, he prays hurriedly, giving only lip service to Hashem, while his heart is preoccupied with foreign thoughts. Then immediately after he finishes praying he runs to eat and drink. Concerning such a one the verse declares, “He labors with iniquity and brings forth falsehood” (Tehillim 7:15). Then, one day death suddenly strikes and the person discovers that he has prepared no provisions for the journey that lies before him.
