Quotation к Мелахим А 2:1

ויהי בארבעים שנה בעשתי עשר חדש באחד לחדש AND IT CAME TO PASS IN THE FORTIETH YEAR, IN THE ELEVENTH MONTH, ON THE FIRST OF THE MONTH, [MOSES SPAKE] — This tells us that he reproved them only shortly before his death (Jewish tradition holds that Moses died on the seventh day of the twelfth month; cf. Megillah 13b). From whom did he learn this? From Jacob, who reproved his sons only shortly before his death. He said, “Reuben, my son, I will tell you why I have not reproved you for your unfitial conduct during all these years: it was in order that you should not leave me and go and join Esau, my wicked brother". — And on account of four things one should not reprove a person except shortly before one's death: that one should not reprove him and again have to reprove him; and that his fellow whom he reproves should not, when he afterwards happens to see him, feel ashamed before him, etc.; as it is set forth in Siphre. And similarly, Joshua reproved Israel only shortly before his death (cf. Joshua 24:1—29), and so, too, Samuel, as it is said, (I Samuel 12:3) “Behold, testify against me", and so, also, David reproved his son Solomon only shortly before his death (cf. 1 Kings 2:1—9).
