וַיַּעַבְד֤וּ הָעָם֙ אֶת־יְהוָ֔ה כֹּ֖ל יְמֵ֣י יְהוֹשֻׁ֑עַ וְכֹ֣ל ׀ יְמֵ֣י הַזְּקֵנִ֗ים אֲשֶׁ֨ר הֶאֱרִ֤יכוּ יָמִים֙ אַחֲרֵ֣י יְהוֹשׁ֔וּעַ אֲשֶׁ֣ר רָא֗וּ אֵ֣ת כָּל־מַעֲשֵׂ֤ה יְהוָה֙ הַגָּד֔וֹל אֲשֶׁ֥ר עָשָׂ֖ה לְיִשְׂרָאֵֽל׃
約書亞在世的日子，以及約書亞死後還活著的那些長老在世的日子，百姓都事奉永恆者；這些長老曾親眼看見永恆者為以色列所行的一切大事。
Rashi
אחרי מותי כי השחת תשחתון [FOR I KNOW THAT] AFTER MY DEATH YE WILL UTTERLY CORRUPT YOURSELVES — But, you see, as a matter of fact, that all the days of Joshua they did not corrupt themselves, for it states, (Judges 2:7) “And the people served the Lord all the days of Joshua”?! (How, then, could Moses say that they would corrupt themselves after his death, by which he evidently meant immediately after his death, cf. v. 16)? But we may derive from here that one’s pupil should be as dear to him as his own self: — it appeared to Moses that so long as Joshua would live it would be as though he himself would be living (he thus alluded by the words “after my death” to a period after Joshua’s death).
