Numerology: Shema and the Cities of Refuge

וְאֵ֣ת הֶֽעָרִ֗ים אֲשֶׁ֤ר תִּתְּנוּ֙ לַלְוִיִּ֔ם אֵ֚ת שֵׁשׁ־עָרֵ֣י הַמִּקְלָ֔ט אֲשֶׁ֣ר תִּתְּנ֔וּ לָנֻ֥ס שָׁ֖מָּה הָרֹצֵ֑חַ וַעֲלֵיהֶ֣ם תִּתְּנ֔וּ אַרְבָּעִ֥ים וּשְׁתַּ֖יִם עִֽיר׃

The towns that you assign to the Levites shall comprise the six cities of refuge that you are to designate for a manslayer to flee to, to which you shall add forty-two towns.

שְׁמַ֖ע יִשְׂרָאֵ֑ל יְהֹוָ֥ה אֱלֹהֵ֖ינוּ יְהֹוָ֥ה ׀ אֶחָֽד׃

Hear, O Israel! The ETERNAL is our God, the ETERNAL alone.

וְתוּ לֵיכָּא? וְהָא כְּתִיב: ״וַעֲלֵיהֶם תִּתְּנוּ אַרְבָּעִים וּשְׁתַּיִם עִיר״! אָמַר אַבָּיֵי: הַלָּלוּ, קוֹלְטוֹת בֵּין לְדַעַת בֵּין שֶׁלֹּא לְדַעַת. הַלָּלוּ – לְדַעַת קוֹלְטוֹת, שֶׁלֹּא לְדַעַת אֵינָן קוֹלְטוֹת.

The Gemara asks: And are there no more cities of refuge beyond these six? But isn’t it written: “And the cities that you shall give to the Levites: The six cities of refuge you shall give for the murderer to flee there, and beyond them you shall give forty-two cities” (Numbers 35:6), indicating that the status of all the Levite cities is that of cities of refuge? Abaye said: With regard to these six cities designated specifically for this purpose, unintentional murderers in need of refuge are admitted there whether they entered the cities deliberately, aware that they are cities of refuge, or whether they entered inadvertently. By contrast, with regard to those forty-two Levite cities, unintentional murderers are admitted only if they entered the cities deliberately, but if they entered the cities inadvertently, they are not admitted to the cities.
