'Statute Forever' in the Bible

As for the assembly, there shall be one [and the same] statute for you [of the congregation] and for the stranger who is a resident alien with you, a permanent statute throughout your generations; as you are, so shall the stranger be before the Lord.

Only the Levites shall perform the service of the Tent of Meeting (tabernacle), and they shall bear their iniquity; it shall be a statute forever throughout your generations, that the Levites shall have no inheritance [of land] among the children of Israel.
