All [these] cities [were given] to the sons of Merari according to the families of them that were left out of the tribe of Levi; and their limits were the twelve cities.
LXX2012
Joshua 21:40
and their suburbs round about these cities: a city and the suburbs round about the city to all these cities: and Joshua ceased dividing the land by their borders: and the children of Israel gave a portion to Joshua because of the commandment of the Lord: they gave him the city which he asked: they gave him Thamnasachar in mount Ephraim; and Joshua built the city, and lived in it: and Joshua took the knives of stone, wherewith he circumcised the children of Israel that were born in the desert by the way, and put them in Thamnasachar.
