“That we are commanded to take possession of the Land which the Almighty, Blessed Be He, gave to our forefathers, to Avraham, to Yitzchak, and to Yaakov; and not to abandon it to other nations, or to leave it desolate, as He said to them, “You shall dispossess the inhabitants of the Land and dwell in it, for I have given the Land to you to possess it,” and he said, further, “To Inherit the Land which I swore to your forefathers (to give them)”; behold, we are commanded with the conquest of the land in every generation.”
Chazal made many other such emphatic statements regarding this positive commandment that we are commanded to possess the Land and settle it. It is therefore an eternal positive command, obligating every single individual even during the time of Exile as is known from the Talmud in many places.
