מוסר אויף קהלת 10:12

Love of The Holy one, blessed be He: There is no better trait than the Love of The Holy one, blessed by He, for the entire service of G-d and Judaism draws from it. To serve (G-d) from love is not comparable to serving from fear, as the author of the "Sefer HaBris" delved and expounded to explain the root of love and fear very well. "The words of the mouth of the wise is grace" (Ecclesiastes 10:12). Praiseworthy is the man who is diligent with his words. To make habit the work which is before me I will come in short, and I will write some notes for myself and for others in my condition, according to that which I learned from the book quoted earlier ("Sefer HaBris") and other books which I have seen to be a reminder between my eyes, and may G-d the Almighty assist me in the matter of honoring His name.

Kohelet 12,13 states: "The sum of the matter, when all has been considered: 'Fear the Lord and keep His commandments, for that is man's whole duty.'" This is a reference to the commandment stated in our portion to revere G–d, to serve Him, to cleave to Him and to swear in His name. It is a commandment of a general all-embracing nature. Because the commandment covers so much ground, the Torah introduces it (10,12) with the words: "And now, what does the Lord ask of you, etc.?" I have explained the meaning of יראת שמים reverence for G–d, at length in my treatise עשרה מאמרים. It includes awareness of the unity of G–d as well as serving the Lord, especially the commandments listed in this פרשה. This commandment includes that we must be aware of G–d's unity and the need to serve Him. Why would the Torah have to tell us separately to swear by the name of G–d only? The reason must be that the very mention of G–d's name one reminds one of the duty to serve Him and to revere Him. Once one does so one would certainly not perjure oneself.

The second is because the repentance of one involved in evil speech is difficult, since he has taught his tongue to speak falsehood, and sent his mouth to evil. From so much habit, he does not control his spirit, and it is as if his mouth causes the thought - like the matter that is stated (Psalms 52:4), “Your tongue devises mischief”; and it is stated (Ecclesiastes 10:12), “but a fool’s lips will swallow him up”; and it is stated.(Proverbs 18:7), “The fool’s speech is his ruin (mechitah).” And mechitah is an expression of fear and trepidation. It means to say that the fool is afraid and in trepidation from the rage of his tongue, lest he be ensnared - like he fears from his enemy - as his lips are not in his control.
