(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 argument that is for [the sake of] heaven's name, it is destined to endure. But if it is not for [the sake of] heaven's name -- it is not destined to endure. What is [an example of an argument] for [the sake of] heaven's name? The argument of Hillel and Shammai. What is [an example of an argument] not for [the sake of] heaven's name? The argument of Korach and all of his congregation.
Rabbi Abba said in the name of Shmuel, For three years, the House of Hillel and the House of Shammai argued. One said, 'The halakha is like us,' and the other said, 'The halakha is like us.' A heavenly voice spoke: "These and these are the words of the living God, and the halakha is like the House of Hillel." A question was raised: Since the heavenly voice declared: "Both these and those are the words of the Living God," why was the halacha established to follow the opinion of Hillel? It is because the students of Hillel were kind and gracious. They taught their own ideas as well as the ideas from the students of Shammai. Not only for this reason, but they went so far as to teach Shammai's opinions first.
The Place Where We Are Right
by Yehuda Amichai
From the place where we are right
Flowers will never grow
In the spring.
The place where we are right
Is hard and trampled
Like a yard.
But doubts and loves
Dig up the world
Like a mole, a plow.
And a whisper will be heard in the place
Where the ruined
House once stood.
