וַיֹּ֣אמֶר אֲלֵהֶ֗ם בֶּן־מֵאָה֩ וְעֶשְׂרִ֨ים שָׁנָ֤ה אָנֹכִי֙ הַיּ֔וֹם לֹא־אוּכַ֥ל ע֖וֹד לָצֵ֣את וְלָב֑וֹא וַֽיהוָה֙ אָמַ֣ר אֵלַ֔י לֹ֥א תַעֲבֹ֖ר אֶת־הַיַּרְדֵּ֥ן הַזֶּֽה׃
곧 그들에게 이르되 내가 오늘날 일백이십 세라 내가 더는 출입하기 능치 못하고 여호와께서도 내게 이르시기를 너는 이 요단을 건너지 못하리라 하셨느니라
Kiddushin
And from where [do we know] that Moshe was born on the seventh of Adar? As it is stated (Deuteronomy 31:2), "And he said to them, 'I am a hundred and twenty year today, I cannot still go out and come in.'" Since there is nothing to learn from saying, "today," what is there to learn from saying "today?" It teaches that the Holy One, blessed be He, sits and fills the number of the years of the righteous ones from day to day and from month to month, as it is stated (Exodus 23:26), "'and I will fill the number of your days.'"
