You shall set apart three cities for you in the midst of your land, which the LORD your God gives you to possess it.
Read Chapter 19
George Leo Haydock
Cities. These were Hebron, Sichem, and Cades, on the west side of the Jordan, Josue xx. 7. Those on the east were already appointed, chap. iv. 41. Three others might also have been added, (ver. 8.; Calmet) in case the Hebrews had gotten full possession of the countries as far as the Euphrates. (Haydock)
The cities of refuge were not above forty-five miles distant from each other, in the land of Chanaan. Those in Galaad were not so far off, as the territory was smaller. (Calmet)
