Ether 13:8

wherefore the remnant of the house of Joseph shall be built upon this land; and it shall be a land of their inheritance; and they shall build up a holy city unto the Lord, like unto the Jerusalem of old; and they shall no more be confounded, until the end come, when the earth shall pass away.

So Joseph’s family who are left will be built upon this land. It will be their land. They will build up a holy city for the Lord. It will be like the old Jerusalem. They will not be confused anymore until the end comes. Then the earth will pass away.

The descendants of Joseph will be established on this land. It will be their inheritance. They’ll build a holy city to the Lord, like the ancient Jerusalem. They won’t be scattered again until the end comes and the earth passes away.
