Sforno on Exodus 33:11/ספורנו על שמות ל״ג:י״א

1פנים אל פנים, as opposed to נופל וגלוי עינים, (Numbers 24,4) as Bileam described his visions which came to him only when he had lost control over his own senses.

2כאשר ידבר איש אל רעהו, as opposed to soliloquizing, [as in praying but not receiving an answer.]

3לא ימיש מתוך האוהל, in order to ensure that none of the Israelites would enter this tent, seeing all of them were in a state of disgrace. This tent was reserved for the presence of the Shechinah out of bounds, as in Exodus 3,5 where Moses was warned not to come close while wearing footwear. The reason that at that time even Moses was not admitted as he was, shows that he was not yet spiritually equipped for that degree of communication from G’d.
