"whither you came to inherit them, from before you": in reward for coming, you will inherit.
"and you inherit them and dwell in their land": Because it is written (Ibid. 19:1) "and you inherit them and you dwell in their cities and in their houses, I might think that you may not add to the building; it is, therefore, written "and dwell in their land" — wherever you wish to build, build.
"and dwell in their land": It happened with R. Yehudah b. Betheira, R. Mathia b. Charash, R. Chanina b. Achi, R. Yehoshua and R. Yonathan, who were traveling abroad and arrived at Paltom, that they remembered Eretz Yisrael, whereupon they raised their eyes and wept and rent their garments, and recited this verse: "Take heed and hearken to all of these things … and dwell in their land" — at which they said: Dwelling in Eretz Yisrael is over and against all of the mitzvoth in the Torah — and they returned and came to their place.
