Numbers 36:1-3

1Then the heads of the clans of Gilead—descendants of Makir, son of Manasseh, son of Joseph—came to Moses and the family leaders of Israel with a petition.

2They said, “Sir, the Lord instructed you to divide the land by sacred lot among the people of Israel. You were told by the Lord to give the grant of land owned by our brother Zelophehad to his daughters.

3But if they marry men from another tribe, their grants of land will go with them to the tribe into which they marry. In this way, the total area of our tribal land will be reduced.
