Musar su Esodo 20:2

Commandment 25 of the 613 commandments is אנכי ה' אלוקיך, "I am the Lord Your G–d."

The commandments: "I am the Lord your G–d," and "you must not have any other god," tell us that אנכי, "I am the Lord your G–d," is the source of all positive commandments, and לא יהיה לך tells us that the same G–d is the source of all negative commandments. Our sages teach us that Israel heard these two commandments directly from G–d's mouth (Makkot 24). This is why you find that G–d addresses Israel in the second person in these two commandments. When G–d introduces the third commandment, He switches half-way through the commandment (20,7) to indirect speech, i.e. כי לא ינקה, "For He will not consider blameless, etc." He also did not say "Do not utter My name in vain, but "do not utter the name of the Lord your G–d in vain." It was Moses quoting G–d who said these words; hence the change in style. The same applies to the remainder of the first set of the Ten Commandments.

Trust is impossible without faith, as it is written : "And they that know Thy Name will put their trust in Thee" (Ps. 9:11). For those who know His Great Name and recognize His greatness and power, and believe in Him with all their heart — only they can truly trust in Him, for trust and faith are partners; if there is no faith, there is no trust. And faith is the very beginning of the Torah, as it is written : "I am the Lord, your God; you shall have no other gods" (Exod. 20:2-3). And if a man does not believe of what good is his Torah? And where a man believes from the depths of his heart that the Creator will fulfill all that is written in the Torah, sending troubles to the sinner and paying a good reward to those who fulfill the precepts of the Torah, then he will carefully guard the Torah. For if all the thieves and robbers knew with certainty that they would be slain because of their thefts and robberies and would be unable to escape this fate, they would restrain themselves from wrong doing. But all of the thieves and robbers are sure that they will always be saved from this tragic end, and, therefore, they do what their heart desires. And, also, in the case of the sinner, if he believed with certainty that he would be punished greatly, he would not sin.
