parshat Chayyei Sarah: Proof of Gilgul

We find evidence for the idea of gilgul in the first pasuk of this week's parsha. The parsha begins {Bereishit 23:1}:

א וַיִּהְיוּ חַיֵּי שָׂרָה, מֵאָה שָׁנָה וְעֶשְׂרִים שָׁנָה וְשֶׁבַע שָׁנִים--שְׁנֵי, חַיֵּי שָׂרָה.

1 And the life of Sarah was a hundred and seven and twenty years; these were the years of the life of Sarah.

And the pasuk states שְׁנֵי חַיֵּי שָׂרָה.

Alternatively, the pasuk begins יִּהְיוּ חַיֵּי שָׂרָה and then states:
מֵאָה שָׁנָה
וְעֶשְׂרִים שָׁנָה
וְשֶׁבַע שָׁנִים

Yes, it's a joke.
