Numbers 36:7-9

7So no inheritance may be passed from tribe to tribe among Bnei-Yisrael—each one of Bnei-Yisrael will each keep the inheritance of the tribe of his ancestors.

8Every daughter receiving an inheritance in one of the tribes of Bnei-Yisrael should marry within the family of her father’s tribe, so that Bnei-Yisrael will each possess the inheritance of his fathers.

9No inheritance may pass from tribe to another tribe, for each tribe of Bnei-Yisrael is to keep its inheritance.”
