(5) But for your own life-blood I will require a reckoning: I will require it of every beast; of man, too, will I require a reckoning for human life, of every man for that of his fellow man!
(א) הוֹאִיל וֶהֱיוֹת הַגּוּף בָּרִיא וְשָׁלֵם מִדַּרְכֵי הַשֵּׁם הוּא. שֶׁהֲרֵי אִי אֶפְשָׁר שֶׁיָּבִין אוֹ יֵדַע דָּבָר מִידִיעַת הַבּוֹרֵא וְהוּא חוֹלֶה. לְפִיכָךְ צָרִיךְ לְהַרְחִיק אָדָם עַצְמוֹ מִדְּבָרִים הַמְאַבְּדִין אֶת הַגּוּף. וּלְהַנְהִיג עַצְמוֹ בִּדְבָרִים הַמַּבְרִין וְהַמַּחֲלִימִים. וְאֵלּוּ הֵן: לְעוֹלָם לֹא יֹאכַל אָדָם אֶלָּא כְּשֶׁהוּא רָעֵב. וְלֹא יִשְׁתֶּה אֶלָּא כְּשֶׁהוּא צָמֵא. וְאַל יַשְׁהֵא נְקָבָיו אֲפִלּוּ רֶגַע אֶחָד. אֶלָּא כָּל זְמַן שֶׁצָּרִיךְ לְהַשְׁתִּין אוֹ לְהָסֵךְ אֶת רַגְלָיו יַעֲמֹד מִיָּד:
(1) Seeing that the maintenance of the body in a healthy and sound condition is a God-chosen way, for it is impossible that one should understand or know any amount of the divine knowledge concerning the Creator when he is sick, it is necessary for man to distance himself from things which destroy the body, and accustom himself in things which are healthful and life-imparting...
(ז) הָרוֹאֶה חֲבֵרוֹ שֶׁחָטָא אוֹ שֶׁהָלַךְ בְּדֶרֶךְ לֹא טוֹבָה מִצְוָה לְהַחֲזִירוֹ לַמּוּטָב וּלְהוֹדִיעוֹ שֶׁהוּא חוֹטֵא עַל עַצְמוֹ בְּמַעֲשָׂיו הָרָעִים שֶׁנֶּאֱמַר (ויקרא יט יז) "הוֹכֵחַ תּוֹכִיחַ אֶת עֲמִיתֶךָ".
(7) He who beholds his fellow stooping to sin or following an unrighteous path, is obliged to return him toward the good, and to let him know that he is actually sinning against himself in pursuing wicked deeds for, it is said: "And thou shalt indeed rebuke thy neighbor" (Lev. 19.17).
One time, a particular man who was a nazirite came from the South and I saw that he had beautiful eyes and was good looking, and the fringes of his hair were arranged in curls. I said to him: My son, what did you see that made you decide to destroy this beautiful hair of yours by becoming a nazirite? A nazirite must shave off his hair at the completion of his term. If he becomes impure before the completion of his term, he shaves off his hair and starts his term of naziriteship again. He said to me: I was a shepherd for my father in my city, and I went to draw water from the spring, and I looked at my reflection [babavua] in the water and my evil inclination quickly overcame me and sought to expel me from the world. I said to myself: Wicked one! Why do you pride yourself in a world that is not yours? Why are you proud of someone who will eventually be food in the grave for worms and maggots, i.e., your body? I swear by the Temple service that I shall shave you for the sake of Heaven.
