(יז) כָּל מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, סוֹפָהּ לְהִתְקַיֵּם. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, אֵין סוֹפָהּ לְהִתְקַיֵּם. אֵיזוֹ הִיא מַחֲלֹקֶת שֶׁהִיא לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת הִלֵּל וְשַׁמַּאי. וְשֶׁאֵינָהּ לְשֵׁם שָׁמַיִם, זוֹ מַחֲלֹקֶת קֹרַח וְכָל עֲדָתוֹ:
(17) Every dispute that is for the sake of Heaven, will in the end endure; But one that is not for the sake of Heaven, will not endure. Which is the controversy that is for the sake of Heaven? Such was the controversy of Hillel and Shammai. And which is the controversy that is not for the sake of Heaven? Such was the controversy of Korah and all his congregation.
(יב) אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי, עָתִיד הַקָּדוֹשׁ בָּרוּךְ הוּא לְהַנְחִיל לְכָל צַדִּיק וְצַדִּיק שְׁלשׁ מֵאוֹת וַעֲשָׂרָה עוֹלָמוֹת, שֶׁנֶּאֱמַר (משלי ח), לְהַנְחִיל אֹהֲבַי יֵשׁ וְאֹצְרֹתֵיהֶם אֲמַלֵּא. אָמַר רַבִּי שִׁמְעוֹן בֶּן חֲלַפְתָּא, לֹא מָצָא הַקָּדוֹשׁ בָּרוּךְ הוּא כְּלִי מַחֲזִיק בְּרָכָה לְיִשְׂרָאֵל אֶלָּא הַשָּׁלוֹם, שֶׁנֶּאֱמַר (תהלים כט), ה' עֹז לְעַמּוֹ יִתֵּן ה' יְבָרֵךְ אֶת עַמּוֹ בַשָּׁלוֹם:
(12) Rabbi Yehoshua ben Levi said: In the world to come the Holy One, Blessed be He, will make each righteous person inherit three hundred and ten worlds, for it is written: "That I may cause those that love me to inherit yesh (numerical value of; and that I may fill their treasuries" (Proverbs 8:2. Rabbi Shimon ben Halafta said: the Holy One, Blessed be He, found no vessel that could contain blessing for Israel save that of peace, as it is written: "The Lord will give strength unto his people; the Lord will bless his people with peace."

In the case of a woman who is a sotah (suspected adulteress), the process of—hopefully—clearing her of suspicion involves erasing the name of G‑d. Based on this, our sages say: “The power of peace is so great . . . that G‑d’s holy name, written in holiness, is erased in water in order to bring peace between the sotah and her husband.”
(יב) הִלֵּל וְשַׁמַּאי קִבְּלוּ מֵהֶם. הִלֵּל אוֹמֵר, הֱוֵי מִתַּלְמִידָיו שֶׁל אַהֲרֹן, אוֹהֵב שָׁלוֹם וְרוֹדֵף שָׁלוֹם, אוֹהֵב אֶת הַבְּרִיּוֹת וּמְקָרְבָן לַתּוֹרָה:
(12) Hillel and Shammai received [the oral tradition] from them. Hillel used to say: be of the disciples of Aaron, loving peace and pursuing peace, loving mankind and drawing them close to the Torah.
(א) אֵלּוּ דְבָרִים שֶׁאֵין לָהֶם שִׁעוּר. הַפֵּאָה, וְהַבִּכּוּרִים, וְהָרֵאָיוֹן, וּגְמִילוּת חֲסָדִים, וְתַלְמוּד תּוֹרָה. אֵלּוּ דְבָרִים שֶׁאָדָם אוֹכֵל פֵּרוֹתֵיהֶן בָּעוֹלָם הַזֶּה וְהַקֶּרֶן קַיֶּמֶת לוֹ לָעוֹלָם הַבָּא. כִּבּוּד אָב וָאֵם, וּגְמִילוּת חֲסָדִים, וַהֲבָאַת שָׁלוֹם בֵּין אָדָם לַחֲבֵרוֹ, וְתַלְמוּד תּוֹרָה כְּנֶגֶד כֻּלָּם:
(1) These are the things that have no definite quantity: The corners [of the field]. First-fruits; [The offerings brought] on appearing [at the Temple on the three pilgrimage festivals]. The performance of righteous deeds; And the study of the torah. The following are the things for which a man enjoys the fruits in this world while the principal remains for him in the world to come: Honoring one’s father and mother; The performance of righteous deeds; And the making of peace between a person and his friend; And the study of the torah is equal to them all.

A story I heard firsthand:
A groom once presented his dilemma to the Rebbe: “I would like my father and father-in-law to escort me to the chupah (wedding canopy), and my mother and mother-in-law to escort my bride—as per Chabad custom. My future in-laws, however, insist that they walk their daughter to the chupah, and that my parents should walk me to the chupah—as is the popular custom amongst most other Orthodox circles. How should we resolve this issue?”
The Rebbe responded: “Since a Jewish minhag (custom) is Torah, you should try to keep your/our minhag. This is true, however, only if you can accomplish this in a peaceful manner. If, however, it will cause discord in the family, you should back down. Since the entire Torah was given only to bring peace to the world,as the verse say : ‘[The Torah’s] ways are pleasant ways, and all its paths are peace,’ it is not logical to allow a minhag to cause a dispute, thus countering the reason and purpose of the entire Torah!”
“Do not remain in a state of dispute with your friend for even one day. And (rather) humble yourself before him and be the first to ask for forgiveness.”
הקדמה
Ahithophel, King David’s wisest advisor, joined the side of Absalom son of David in his rebellion against his father. When Ahithophel realized that King David’s side would be victorious, he went home to give his children his last will and testament, and then committed suicide. One of the pieces of advice he gave them was: Do not get involved in disputes—this after he realized that his involvement in a dispute cost him his life.
