Inheritance of Zelophehad’s daughters

Numbers 36:1-13
Then at the Lord’s command Moses gave this order to the Israelites: “What the tribe of the descendants of Joseph is saying is right. This is what the Lord commands for Zelophehad’s daughters: They may marry anyone they please as long as they marry within their father’s tribal clan. No inheritance in Israel is to pass from one tribe to another, for every Israelite shall keep the tribal inheritance of their ancestors.  Every daughter who inherits land in any Israelite tribe must marry someone in her father’s tribal clan, so that every Israelite will possess the inheritance of their ancestors.  No inheritance may pass from one tribe to another, for each Israelite tribe is to keep the land it inherits.”
Zelophehad’s daughters—Mahlah, Tirzah, Hoglah, Milkah and Noah—married their cousins on their father’s side. They married within the clans of the descendants of Manasseh son of Joseph, and their inheritance remained in their father’s tribe and clan.
Why? 
Israelite follow the word of Moses let Zelophehad’s daughters may get the land by lot and have the inheritance for themselves.
The spirit is that for each Israelite tribe is to keep the land it inherits.
Keep the tribal inheritance of their ancestors, another spirit is keep the faith to the Lord as their ancestors. It is the Lord lead Israelite out from Egypt, the slave, to the promised land, to be free.
How?
Keep the faith to the Lord for God loves us. Let this faith being kept in my inheritance.
