Литература Второго Храма к Бамидбар 35:12

וְהָי֨וּ לָכֶ֧ם הֶעָרִ֛ים לְמִקְלָ֖ט מִגֹּאֵ֑ל וְלֹ֤א יָמוּת֙ הָרֹצֵ֔חַ עַד־עָמְד֛וֹ לִפְנֵ֥י הָעֵדָ֖ה לַמִּשְׁפָּֽט׃

И города будут для тебя убежищем от Мстителя, чтобы убийца не умер, пока не предстанет перед собранием для суда.

[100] Such are the six cities, which Moses calls “places of refuge” (Num. 35:12), five of which were represented by symbolic figures which are in the sanctuary, the Laws laid up in the ark being symbols of injunction and prohibition; the lid of the ark, which he calls the Mercy-seat, representing the gracious power; while the creative and kingly powers are represented by the winged Cherubim that rest upon it.
