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׃
免得報血仇的人心中火熱，追趕那殺人的，因路途遙遠就追上他，將他擊殺；其實他本不該被判死罪，因為他與那人素來並無仇恨。
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].
