Joshua 21:38-45

38 And out of the tribe of Gad, Ramoth in Gilead with her suburbs, to be a city of refuge for the slayer; and Mahanaim with her suburbs,
39 Heshbon with her suburbs, Jazer with her suburbs; four cities in all.
40 So all the cities for the children of Merari by their families, which were remaining of the families of the Levites, were by their lot twelve cities.
41 All the cities of the Levites within the possession of the children of Israel were forty and eight cities with their suburbs.
42 These cities were every one with their suburbs round about them: thus were all these cities.
43 And the LORD gave unto Israel all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein.
44 And the LORD gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the LORD delivered all their enemies into their hand.
45 There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.
