Бамидбар 35:6 Ссылки в Мишне: Mishnah Makkot

To where are they banished? To the cities of refuge, to the three cities situated on the far side of the Jordan and the three cities situated in Canaan, as it says, “Three cities shall be designated beyond the Jordan, and the other three shall be designated in the land of Canaan” (Numbers 35:14). Not until three cities were selected in the land of Israel did the [first] three cities beyond the jordan receive fugitives, as it says, “Six cities of refuge in all” (Numbers 35:13), until all six could simultaneously receive fugitives.

If the trial was concluded when there was no high priest [in office], or if one kills a high priest, or a high priest that kills, [in these cases the manslayer] can never come away from that place [of refuge]. He [the manslayer] may not go out to bear witness, neither for cases having to do with a religious observance, nor to bear witness in a monetary suit, nor to bear witness in a capital case. Even should [all] Israel need him, and even a general like Yoav the son of Zeruiah, he may never go out, as it is said, “to there he fled”: ‘there’ must be his abode, ‘there’ his death, ‘there’ his burial. Just as the city affords asylum so does its Sabbath boundary afford asylum. If a manslayer went beyond the boundary [of the city] and the blood avenger found him: Rabbi Yose the Galilean says: “For the avenger it is a matter of obligation [to kill him]; for everyone else, a matter of option.” Rabbi Akiba says: “It is a matter of option for the avenger, and anyone else [who kills him] is not liable for doing so.” If a tree was standing within the boundary and its boughs extended beyond [the boundary] or if it was standing outside of the boundary and its boughs extended within, it wholly follows [the position of] the boughs. If he slew [someone] in that city [of refuge] he is banished from one neighborhood to another neighborhood. And a Levite is banished from one city to another.
