'Added' in the Bible

Now if they be married to any of the sons of the other tribes of the children of Israel, then shall their inheritance be taken from the inheritance of our fathers, and shall be added to the inheritance of the tribe to which they shall belong; and it shall be taken from the lot of our inheritance.

And when the jubilee of the children of Israel shall come, then shall their inheritance be added to the inheritance of the tribe to which they shall belong; and their inheritance shall be taken away from the inheritance of the tribe of our fathers.
