Se’if 1א׳
צָרִיךְ לִזָּהֵר מְאֹד בִּכְבוֹד אָבִיו וְאִמּוֹ וּבְמוֹרָאָם. הַגָּה: וּמִכָּל מָקוֹם אֵין בֵּית דִּין כּוֹפִין עַל מִצְוַת כִּבּוּד אָב וָאֵם, דְּהָוֵי לֵיהּ מִצְוַת עֲשֵׂה שֶׁמַּתַּן שְׂכָרָהּ בְּצִדָּהּ שֶׁאֵין בֵּית דִּין כּוֹפִין עָלֶיהָ (בֵּית יוֹסֵף בְּשֵׁם הַגְּמָרָא ובתא"ו נָתִיב א').
What is honor and what is fear, and their laws. Containing 25 paragraphs. One must be very careful concerning his father and mother's honor and fear. Rema: But nevertheless, the court does not enforce the honor of father and mother; since it is a positive commandment the reward of which is alongside it, such that the court does not enforce it (Beit Yosef in the name of the Gemara; Toledot Adam VeChava, Netiv A).
Se’if 2ב׳
אֵיזֶה מוֹרָא, לֹא יַעֲמֹד בִּמְקוֹמוֹ הַמְיֻחָד לוֹ לַעֲמֹד שָׁם בְּסוֹד זְקֵנִים עִם חֲבֵרָיו, אוֹ מָקוֹם הַמְיֻחָד לוֹ לְהִתְפַּלֵּל; וְלֹא יֵשֵׁב בְּמָקוֹם הַמְיֻחָד לוֹ לְהָסֵב בְּבֵיתוֹ; וְלֹא סוֹתֵר אֶת דְּבָרָיו וְלֹא מַכְרִיעַ אֶת דְּבָרָיו בְּפָנָיו, אֲפִלּוּ לוֹמַר נִרְאִין דִּבְרֵי אַבָּא; וְלֹא יִקְרָאֶנּוּ בִּשְׁמוֹ, לֹא בְּחַיָּיו וְלֹא בְּמוֹתוֹ, אֶלָּא אוֹמֵר: אַבָּא מָארִי. הָיָה שֵׁם אָבִיו כְּשֵׁם אֲחֵרִים, מְשַׁנֶּה שְׁמָם, אִם הוּא שֵׁם שֶׁהוּא פִּלְאִי, שֶׁאֵין הַכֹּל רְגִילִים לִקְרוֹת בּוֹ. אֲבָל שֵׁם שֶׁרְגִילִין בּוֹ מֻתָּר לִקְרוֹת אֲחֵרִים שֶׁלֹּא בְּפָנָיו (טוּר).
What is fear? He should not stand in the place designated for him to stand in the consultation of the elders with his colleagues, or the place designated for him to pray, nor should he sit in the place designated for him to recline in his home, nor contradict his words nor determine his words in his presence - even to say, "Father's words appear [correct]." And he should not call him by his name, neither in life nor in death, but rather say, "Father, my teacher." If his father's name was like the name of others, he changes their names if it is an unusual name that not all of the people call [their offspring] with. But it is permissible to call others with a name that is [common], not in front of him (Tur).
Se’if 3ג׳
עַד הֵיכָן מוֹרָאָם, הָיָה הַבֵּן לָבוּשׁ חֲמוּדוֹת וְיוֹשֵׁב בְּרֹאשׁ הַקָּהָל, וּבָאוּ אָבִיו וְאִמּוֹ וְקָרְעוּ בְּגָדָיו וְהִכּוּהוּ עַל רֹאשׁוֹ וְיָרְקוּ בְּפָנָיו, לֹא יַכְלִים אוֹתָם, אֶלָּא יִשְׁתֹּק, וְיִירָא מִן מֶּלֶךְ מַלְכֵי הַמְּלָכִים שֶׁצִּוָּהוּ בְּכָךְ.
To what extent is their fear? Had the son been dressed with fine clothing and sitting at the head of the community, and his father and mother came and ripped his clothes, hit him on his head and spit in front of him - he should not shame them, but rather remain silent, and fear the King of kings of kings, who so commanded him.
