- The gemara in Taanis 21a brings a story about Nachum Ish Gamzu that explains why he was called "Ish Gamzu", because he would always say "Gam Zu L'tovah" (This too is for the best).
- It is also known that Rabbi Akiva would always say ״כׇּל דְּעָבֵיד רַחֲמָנָא לְטָב עָבֵיד״ (Everything that God does, He does for the best) from the Gemara in Berachos 60b.
My question: We know that Rabbi Akiva was the student of Nachum Ish Gamzu, so why didn't he use the same phrase that his rebbi would use?
