Halakhah do Liczb 35:7

The commandment on Israel to give cities within which the Levites may dwell, and they shelter: That Israel was commanded to give cities to the Tribe of Levi to dwell therein, since they do not have a portion in the Land, as it is stated (Numbers 35:2), "Command the Children of Israel, and they shall give to the Levites from the inheritance of their holding, cities to dwell." And it is stated at the end of the section (Numbers 35:7). "All of the cities that you shall give to the Levites are forty-eight cities." And from these forty-eight cities of the Levites, there were cities that were specified to be a refuge for the killer. However, all of them would shelter him. And with God's help, we will write in the Order of Shoftim in the commandment of the cities of refuge (Sefer HaChinukh 520), what is [the difference] between those specified for this and the others. And they would shelter him in well-known ways, as is explained in Scripture. And it is elucidated in Tractate Makkot 10a.
