Numbers 36:7-9

New Living Translation

⁷ None of the territorial land may pass from tribe to tribe, for all the land given to each tribe must remain within the tribe to which it was first allotted. ⁸ The daughters throughout the tribes of Israel who are in line to inherit property must marry within their tribe, so that all the Israelites will keep their ancestral property. ⁹ No grant of land may pass from one tribe to another; each tribe of Israel must keep its allotted portion of land.”
