אמר להם אידין מתקרי חכים אמרו ליה איזהו חכם הרואה את הנולד אמר להם אידין מתקרי גבור אמרו לו איזהו גבור הכובש את יצרו אמר להן אידין מתקרי עשיר אמרו ליה איזהו עשיר השמח בחלקו
Alexander said to the Elders: Who is truly worthy of being called wise? They said to him, citing a tradition (see Avot 2:9): Who is the wise person? The one who sees and anticipates the consequences of his behavior. He said to them: Who is truly worthy of being called mighty? They said to him, again citing a tradition (see Avot 4:1): Who is the mighty person? The one who masters his desire. He said to them: Who is worthy of being called wealthy? They said to him: Who is the wealthy person? The one who is pleased with his own portion (see Avot 4:1).
