וּמָצָ֤א אֹתוֹ֙ גֹּאֵ֣ל הַדָּ֔ם מִח֕וּץ לִגְב֖וּל עִ֣יר מִקְלָט֑וֹ וְרָצַ֞ח גֹּאֵ֤ל הַדָּם֙ אֶת־הָ֣רֹצֵ֔חַ אֵ֥ין ל֖וֹ דָּֽם׃
而報血仇的人在他的避難城邊界以外遇見他，把殺人者殺了，報血仇的人就沒有流血的罪。
Tosefta Terumot
The slave of a priest who escaped, or the wife of a priest who rebelled, behold, they may [nonetheless] eat terumah. And the [inadvertent] killer may not go outside the border of his sanctuary city (Num. 35:27) due to the presumption that that the High Priest is still alive.
