'RShimon ben Menasya says in the name of R' Shimon ben Yochai: Beauty, strength, wealth, honor, [Torah] wisdom, old age and ripe old age, and children, [they] are fitting for the righteous and fitting for the world, as it is stated: The crown of splendor is ripe old age, it will be found in the path of righteousness. And it states: The splendor of youth is their strength, and the glory of the elders is their hoariness. And it states: The crown of the wise is their wealth. And it states: The crown of elders is grandchildren and the glory of children is their parents. And it states: The moon will be humiliated and the sun will be shamed, for Hashem Master of Legions will have reigned in Mount Zion and in Jerusalem, and there will be honor for His elders.  R' Shimon ben Menasya says: These seven qualities that the Sages enumerated [as fitting] for the righteous, all of them were found in Rebbi and in his sons.
