Divide the land among your families by drawing lots. Give bigger portions to larger families and smaller portions to smaller families. Whatever lot falls to each family, that's their land. Divide it up among your ancestors' tribes. Numbers 33:54 - Modern Text Bible

(The land is to be distributed fairly, with the size of each family's share matching their needs, and the process is meant to be impartial.)
