Genesis 25:17 says:
וְאֵלֶּה שְׁנֵי חַיֵּי יִשְׁמָעֵאל מְאַת שָׁנָה וּשְׁלשִׁים שָׁנָה וְשֶׁבַע שָׁנִים וַיִּגְוַע וַיָּמָת וַיֵּאָסֶף אֶל עַמָּיו׃
And these are the years of the life of Ishmael: one hundred years and thirty years and seven years; and he expired and died and was gathered to his people.
What is the reason that the word “years” was written after every digit by Yishmael?
Rashi asks this question by Sarah (Genesis 23:1) and by Avraham ( Genesis 25:7) [lehavdil] but his answer in those cases doesn't seem likely to apply by Yishmael. By Yishmael - Rashi doesn't ask this question at all.
Is there a limud here by Yishmael?
