Joshua 21:39-45 MSG

39 Heshbon, and Jazer, with their pastures - a total of four towns.
40 All these towns were assigned by lot to the Merarites, the remaining Levites - twelve towns.
41 The Levites held forty-eight towns with their accompanying pastures within the territory of the People of Israel.
42 Each of these towns had pastures surrounding it - this was the case for all these towns.
43 And so God gave Israel the entire land that he had solemnly vowed to give to their ancestors. They took possession of it and made themselves at home in it.
44 And God gave them rest on all sides, as he had also solemnly vowed to their ancestors. Not a single one of their enemies was able to stand up to them - God handed over all their enemies to them.
45 Not one word failed from all the good words God spoke to the house of Israel. Everything came out right.
