Numbers 36:6-9 ▼

6 And so, this is the law which has been promulgated by the Lord about the daughters of Zelophehad: Let them marry whomever they may wish, but only among the men of their own tribe,

7 lest the possession of the sons of Israel become commingled, from tribe to tribe. For all men shall take wives from their own tribe and kinship;

8 and all women shall take husbands from their same tribe, so that the inheritance may remain within the families,

9 and so that the tribes may not be mingled together, but may remain such as they were separated by the Lord.”
