Numbers 36:7-9

New Century Version

⁷ In this way the Israelites’ land will not pass from tribe to tribe, and each Israelite will keep the land in the tribe that belonged to his ancestors. ⁸ A woman who inherits her father’s land may marry, but she must marry someone from her own tribe. In this way every Israelite will keep the land that belonged to his ancestors. ⁹ The land must not pass from tribe to tribe, and each Israelite tribe will keep the land it received from its ancestors.”
