Furthermore, in my view, his saying "at that time" serves the purpose of apprising us that even after the Jews had sinned in the affair of Peor, the Blessed One was jealous for their honor and did not want to forgive Moses "for their sake." If "at that time" had not been stated, we would get the impression that he implored the L-rd at the time of his sin, before the Peor affair, in which case the Blessed One's concern for their honor would be no great cause for wonder. But "at that time," after they had stumbled into idolatry — with all this, His love did not depart from them. This shows that he related to them as a father to his son, who though he [the son] rebel grievously, he will not cast him from his presence. This is the intent of the concluding statement (Deuteronomy 3:29): "and we sat in the valley opposite Beth Peor." Why is this mentioned here? Only to stress what was stated before, viz.: G-d's becoming angry with me was for your sake and for your honor, after we had sat in the valley opposite Beth Peor and there had transpired what had transpired there (Perish the mention!). And this is the intent of our sages of blessed memory in the afore-mentioned homily (Sifrei, Deuteronomy 29). And it is in this vein that the verse continues (Deuteronomy 4:1): "And now, O Israel, hear the statutes and the judgments…" That is, since you are so greatly beloved by Him it well befits you to hear His statutes and His judgments."
