Sforno on Deuteronomy 4:37/ספורנו על דברים ד׳:ל״ז

1ותחת 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) .

2ויוציאך בפניו, by performing a series of miraculous deeds

3ממצרים, from Egypt; להוריש, G’d intended to take you out of slavery, a state in which you would not have been able to appreciate His intentions.
