פֶּן־יִרְדֹּף֩ גֹּאֵ֨ל הַדָּ֜ם אַחֲרֵ֣י הָרֹצֵ֗חַ כִּי־יֵחַם֮ לְבָבוֹ֒ וְהִשִּׂיג֛וֹ כִּֽי־יִרְבֶּ֥ה הַדֶּ֖רֶךְ וְהִכָּ֣הוּ נָ֑פֶשׁ וְלוֹ֙ אֵ֣ין מִשְׁפַּט־מָ֔וֶת כִּ֠י לֹ֣א שֹׂנֵ֥א ה֛וּא ל֖וֹ מִתְּמ֥וֹל שִׁלְשֽׁוֹם׃
그 사람이 그에게 본래 혐원이 없으니 죽이기에 합당치 아니하나 두렵건대 보수자의 마음이 뜨거워서 살인자를 따르는데 그 가는 길이 멀면 그를 따라 미쳐서 죽일까 하노라
Rashi
Please remember Adonoy. God was stringent concerning the distance [necessary] to save lives2When a person kills accidently, he must go to a city of refuge. These cities should never be too distant from any potential fugitive who may need to go there. as it is said, "He will overtake him because the way was long".3Devorim 19:5. This is [her reference with], "To avoid giving more [time] for the avenger to destroy," and you are pushing me [away].
