וַיָּבִיאוּ אֶת הַמִּשְׁכָּן אֶל מֹשֶׁה. יְלַמְּדֵנוּ רַבֵּנוּ, כַּמָּה דְבָרִים מְתֻקָּנִים מִפְּנֵי דַרְכֵי שָׁלוֹם. כָּךְ שָׁנוּ רַבּוֹתֵינוּ, אֵלּוּ דְבָרִים אָמְרוּ מִפְּנֵי דַרְכֵי שָׁלוֹם, כֹּהֵן קוֹרֵא רִאשׁוֹן וְאַחֲרָיו לֵוִי וְאַחֲרָיו יִשְׂרָאֵל, מִפְּנֵי דַרְכֵי שָׁלוֹם, בֹּא וּרְאֵה כַּמָּה חָבִיב הַשָּׁלוֹם לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא, שֶׁבְּשָׁעָה שֶׁנִּכְנְסוּ לָאָרֶץ, אָמַר הַקָּדוֹשׁ בָּרוּךְ הוּא לְמֹשֶׁה, וְהִתְגָּר בָּם מִלְחָמָה.
And they brought the tabernacle unto Moses (Exod. 39:32). May it please our masters to teach us: What things were instituted for the sake of peace? Thus do our masters teach us: The following were instituted for the sake of peace: The priest shall read from the Torah first, then the Levite, and finally the Israelite, because that is the path of peace. Observe how precious peace is in the sight of the Holy One, blessed be He, that when the time came for them to enter the land, the Holy One, blessed be He, said to Moses: Neither contend with them in battle (Deut. 2:9).¹⁶
