Why does rashbam write "Stam shimon is Rav shimon Ben yochai"
SHMUEL D BERKOVICZ, Lakewood
The Gemara brings R' Shimon Ben Yehuda in the name of R' Shimon . One could ask why isn't the 2nd R' Shimon's father mentioned like the first? Rashbam therefore explains that it is known that R' Shimon always means R' Shimon Bar Yochai.
All the best,
