Joshua 21:2

‘ And they spoke to them at Shiloh in the land of Canaan, saying, “YHWH commanded by the hand of Moses to give us cities to dwell in, with their suburbs for our cattle.” '

The approach would probably be made before the Tent of Meeting with due solemnity. The Levites had a responsibility to Israel in respect of guidance in accordance with the Law, overseeing the tithes, and generally observing that the Law was fulfilled. In return they had to be given cities to dwell in and land for their cattle, but not land to plant and sow.
