Joshua 21:4

And the lot came out for the families of the Kohathites, descendants of the second son of Levi, the families of whose three sons, Izhar, Hebron, and Uzziel, together with the descendants of Moses, formed the division of the Kohathite Levites, while the descendants of Aaron were vested with the priesthood. Note that the cities were selected by the Israelites themselves, but that the Lord decided, by directing the drawing of the lots, which of these cities each particular family should have. And the children of Aaron, the priest, which were of the Levites, descendants of Levi, had by lot out of the tribe of Judah and out of the tribe of Simeon and out of the tribe of Benjamin, all in Southern Canaan, thirteen cities. So it was even at this time that the Lord arranged to settle the priests in the cities near the place where He intended to have the permanent Sanctuary. There is never an element of chance in His government of the world and of His Church.
