Ephraem the Syrian
"Make ready the path to the cities of refuge, ensuring that the journey there is unobstructed, allowing one to reach them easily and evade retribution."
Paving diligently the way: and thou shalt divide the whole province of thy land equally into three parts: that he who is forced to flee for manslaughter, may have near at hand whither to escape.
תָּכִ֣ין לְךָ֮ הַדֶּרֶךְ֒ וְשִׁלַּשְׁתָּ֙ אֶת־גְּב֣וּל אַרְצְךָ֔ אֲשֶׁ֥ר יַנְחִֽילְךָ֖ יְהוָ֣ה אֱלֹהֶ֑יךָ וְהָיָ֕ה לָנ֥וּס שָׁ֖מָּה כָּל־רֹצֵֽחַ׃
