פירוש על דברים 4:37

ותחת כי אהב AND BECAUSE HE LOVED — i.e., and all this was because He loved thy fathers.

ותחת כי אהב את אבותיך, having done all this because He loved your patriarchs, ויבחר בזרעו, He chose the descendants of only one of them (Yaakov) .

ויוציאך בפניו, as documented in Exodus 12,12 and 23,21.
