Talmud for Pirkei Avot 6:12

⁴³Mishnah Avot 6:8, Tosephta Sanhedrin11:8. In these sources, the original author is R. Simeon ben Iohai. Rebbi Simeon ben Menasia says: Beauty, and vigor, and riches, and wisdom, and white hair, and honor, and children, are an adornment for the just. What is the reason? A crown of glory is white hair; on the way of piety it is found⁴⁴Prov. 16:31.. A crown of the elderly are grandchildren; the glory of children are their parents⁴⁵Prov. 17:6.. The glory of the young is their force; the splendor of the elderly is white hair⁴⁶Prov. 20.29.. And it says, before his Elders in honor⁴⁷Is 24:23.. ⁴⁸This sentence has to be deleted since Rebbi’s father cannot speak about his son and grandsons. Since Rebbi was the last of the Tannaïm, only amoraic statements about him are legitimate. It was stated: Rabban Simeon ben Gamliel says, these seven qualities which the Sages enumerated for the just were all realized by Rebbi and his sons. Rebbi Joḥanan said, all seven qualities which the Sages enunciated about the just were in Rebbi. Who was Rebbi? Rebbi is Rebbi Jehudah the Prince. Rebbi Abbahu said, Rebbi is Rebbi Yudan the Prince, is Our Teacher⁴⁹It is not clear whether he refers to R. Jehudah I ben Simeon, mentioned by R. Johanan, or to R. Jehudah II ben Gamliel..

Everything that the Holy Blessed One created in the world was created only for His glory, as it says (Isaiah 43:7), “All that has been called by My name, whom I have created, formed, and made for My glory.” And it also says (Exodus 15:18), “The Eternal will reign forever and ever.”
