Musar su Deuteronomio 4:35

These four qualities are lacking if wisdom is lacking, for they cannot join together unless there be knowledge and wisdom. If a man does not have knowledge and wisdom, he will not recognize his God and serve Him, as it is said (Jeremiah 9:23), “But let him that glorieth glory in this, that he understandeth and knoweth Me.” The Prophet means that everyone who possesses wisdom will understand and know “Me” immediately. For it is through knowledge that a man recognizes his Creator and then serves Him. In this manner, is it explained in many places. Concerning reason, it is said (Deuteronomy 29:8), “In order that you may do everything with intelligence”, and concerning knowledge, it is said (ibid., 4:35), “Unto thee it was shown, that thou mightest know.”

Maimonides, in his ספר המדע writes as follows: "We must appreciate a fundamental truth, something basic to all knowledge. There is a SINGLE original Cause who in turn has created all other phenomena. If you ever were to think that HE does not exist, it would follow that none of the phenomena we perceive exist either. If you could imagine that all other phenomena would cease to exist, HE still would continue to exist, since all phenomena need Him for their continued existence, whereas He does not need them for His existence. His "truth" is therefore not comparable to any other kind of "truth," and this is why the prophet says: וה' אלוקים הוא לבדו אמת, "And the Lord G–d is truth" (Jeremiah 10,10). This is also what the Torah means in Deut. 4,35 ואין עוד מלבדו, "There is no one else beside Him." No truth exists independent of G–d. It is His Existence that is the supreme G–d of the universe, and He guides the universe. It is a positive commandment to acquire knowledge of and guard these facts, for the Torah says: "I am the Lord your G–d, etc." Anyone who entertains the thought that there is any other deity is a כופר בעיקר, violates a fundamental negative commandment, because the Torah says: "You must not have any other god in My Presence." Such a person denies the central pillar of the Jewish faith that everything depends upon Him. Thus far Maimonides.

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).
