Numbers 36:2-4

They said, “When GOD commanded my master to hand over the inheritance-lands by lot to the People of Israel, my master was also commanded by GOD to hand over the inheritance-land of Zelophehad our brother to his daughters. But what happens if they marry into another tribe in the People of Israel? Their inheritance-land will be taken out of our ancestral tribe and get added into the tribe into which they married. And then when the year of Jubilee comes for the People of Israel their inheritance will be lumped in with the inheritance of the tribe into which they married—their land will be removed from our ancestors’ inheritance!”
