Quotation к Шмот 19:16

You were revealed in Your cloud of glory to Your holy people to speak to them. From the heavens, You let them hear Your voice, and revealed Yourself to them in pure clouds. So too, the entire world quivered before You, and the works of creation trembled before You, when You, our King revealed Yourself upon Mount Sinai to teach Your people Torah and mitzvos. You let them hear the majestic splendor of Your voice, and Your holy words from flames of fire; amidst thunder and lightning You revealed Yourself to them, and with the sound of a shofar, You appeared to them, as it is written in Your Torah: “And it was on the third day, as morning dawned there was thunder and lightning, and a dense cloud over the mountain, and the sound of a shofar was exceedingly loud; and all the people in the camp trembled.” And it is said: “And the sound of the shofar became increasingly louder; Moshe spoke and God answered him by voice.” And it is said: “And all the people saw the sounds and the flames, and the sound of the shofar, and the mountain in smoke; and the people saw and were shaken, and stood from afar.”

And so a person [must] remember [this] and take care during his learning the Torah how he speaks the letters of the Torah, for with them was the world created, and by himself attach the letters to their root letters in the Torah, which was given like this to the world through 'thunder and lightening' in order that 'the fear of God should be upon you and you will be without sin', as explained. In any case, if 'awe' and 'fear' befall a person in 'thunder and lightening', its seems apparent that he would not sing, God forbid. For how could there be the possibility of sin with all that. And this is the idea of the 'heavenly voice which goes forth', they are the letter of the Torah inside every person who recalls and declares them daily. And he who doesn't not hear the heavenly voice [and for whom] it is as if he did not declare, 'woe unto him...for insulting the Torah' which is inside of him. And this is the meaning of 'for anyone who does not involve himself in the Torah' meaning - who is not inscribed in the Torah, "he is called "rebuked"'; for this is the idea of rebuke for a person which changes his 'face to redness'
