I think there are two posukim in shas that speak about not walking more then 4 amos without learning Torah (or wearing tefillin) I think the Rabbi was Rav Yochonon. Does the Rav possibly recall the location of these (or one) posukim in shas?
Try Yoma 086a (where Rebbi Yochanan said it would be a Chilul Hash-m for him to walk four Amos without Torah), and Sukah 028a (where Rebbi Yochanan *ben Zakai* is said to have never gone four Amos without Torah). Rebbi Zeira makes a similar claim in Taanis 20b and Megilah 28a.
Thank you, I think there is one missing from Rav Yohoshua ben Karcha, I think but I
don't know where it is. Any thoughts?
Sorry, I couldn't find it. Rebbi Yehoshua ben Korchah *is* mentioned in the Gemara in Megilah 28a referred to above, but it is Rebbi Zeira (who follows his discussion) who makes the statement about not walking without Torah.
