What is the meaning of "v'Hayah Tapilu Osah b'Nachalah Lachem"?
Radak: This is the border that you will cast for an inheritance.
Malbim: This is when you will give to inheritances to individuals.
Why does it say "Lachem uleha'Gerim"?
Radak: It is also for Gerim. There is properly the prefix Hei ha'Yedi'ah (to identify) in uleha'Gerim, just usually when there is also the prefix Lamed, the Hei is omitted [and there is a Patach under the Lamed].
Malbim: This refers to people who already converted. We will not accept converts in the days of Mashi'ach.
Why does it say "Asher Holidu Vanim b'Sochechem"?
Radak: The convert fathered children amidst you in Galus.
