פירוש על בראשית 24:4

כי אם אל ארצי, not to members of any nation which does not dwell physically close to the region from which I originate. This is where you shall go to conduct your search.

כי אל ארצי ואל מולדתי תלך, "rather you shall go to my country and to my birthplace, etc." This was part of the oath also; Eliezer was to secure a wife for Isaac in Abraham's birthplace. This is why Eliezer is described as immediately taking the camels, etc.

כי אם אל ארצי, he referred to Aram Naharyim.
