Mishnà su Proverbi 16:3

Rabbi Shimon ben Menasya said in the name of Rabbi Shimon ben Yohai: Beauty, strength, riches, honor, wisdom, [old age], gray hair, and children are becoming to the righteous, and becoming to the world, As it is said: “Gray hair is a crown of glory (beauty); it is attained by way of righteousness” (Proverbs 16:31), And it says: “The ornament of the wise is their wealth” (ibid. 14:24), And it says: “The glory of youths is their strength; and the beauty of old men is their gray hair” (ibid. 20:29), And it says: “Grandchildren are the glory of their elders, and the glory of children is their parents” (ibid. 17:6), And it says: “Then the moon shall be ashamed, and the sun shall be abashed. For the Lord of Hosts will reign on Mount Zion and in Jerusalem, and God’s Honor will be revealed to his elders” (Isaiah 24:23). Rabbi Shimon ben Menasya said: these seven qualities, which the sages have listed [as becoming] to the righteous, were all of them fulfilled in Rabbi and his sons.
