פּירוש אויף דברים 4:25

ונושנתם AND YE SHALL HAVE BEEN LONG [IN THE LAND] — He gave them a vague intimation that they would be exiled from it at the end of 852 years, according to the numerical value of the word ונושנתם, but He sent them into exile earlier, at the end of 850 years. He did this two years earlier than the numerical value of ונושנתם, in order that the prophecy should not be fulfilled in them “that ye shall utterly perish” (v. 26). This is the meaning of what is said, (Daniel 9:14) “And the Lord hastened in regard to the evil, and He brought it upon us, for the Lord our God is צדיק” — i.e., He acted charitably (צדקה) with us, in that He brought it (the evil) two years before its assigned time (Sanhedrin 38a; Gittin 88a).

כי תוליד בנים ובני בנים, “When you shall beget children, and children’s children;” Moses implies that when he warned the people not to forget the Lord’s covenant, he did not refer to the generation he was addressing. He was not worried that they would forget. What he was concerned about was future generations, who had not been eye witnesses to what the Lord had done for the Jewish people.

כי תוליד בנים וגו, “when you beget children etc.” Moses warns the people not to take their settlement in the land of Israel for granted even after they have lived there for several generations. Their tenure in the land is contingent on their continuing to observe the Torah and all of its commandments. If they failed to do, not only would they endanger their tenure of the land, but they would endanger their continued existence as G–d’s people. [If, say after six generations in the Holy Land, the people who had not been witnesses to all the miracles G–d had performed before the first generation settled in that land, they would claim that there was no reason why their tenure is linked to Torah observance, just as their neighbour’s tenure to their respective lands is not contingent on a set of laws of their religion, Moses warns them against such a fatal error. Ed. According to the Talmud, tractate Sanhedrin, folio 38, the numerical value of the letters in the words: ונושנתם בארץ, “and you will be long established in the land,” (852) אבוד תאבדון, “you will be utterly wiped out in verse 26. G–d did us a great favour when the exile began after 850 years of tenure, so that the threat of utter destruction of the Jewish nation since the time Joshua crossed the Jordan did not have to be fulfilled. This has been hinted at in the Book of Daniel 9,14: וישקוד ה' על הרעה ויביאה עלינו כי צדיק ה' אלוקינו, “Hashem hastened the calamity and brought it upon us, for Hashem is righteous in all He does (but we did not heed His voice).”
