Sforno on Exodus 33:19/ספורנו על שמות ל״ג:י״ט

1אני אעביר כל טובי על פניך, this will not be denied due to My not being unwilling to bestow these insights. As proof,

2אעביר כל טובי על פניך וקראתי בשם ה' לפניך, G’d proclaims what He says using the name of Hashem, the “name” which informs people and teaches them about His existence as the G’d whose ways are those pf goodness. By saying that He will parade all of His goodness before Moses, He implies that if Moses had been capable of understanding all of the hidden aspects of G’d’s essence He would indeed have fulfilled all of Moses’ requests. Nonetheless, i.e. in spite of Moses’ or better, man’s inherent inability to understand all of this, G’d will reveal a fragment of His modus operandi; by doing this Moses would acquire a glimpse of G’d’s essence as portrayed in 34,5.

3וחנותי את אשר אחון, I will grant you the degree of insights I grant all those who find favour in My eyes. I am in the habit of being very generous in the application of this principle.

4ורחמתי את אשר ארחם, I will use My attribute of Mercy so that you will not die during the experience, just as it is My custom to extend mercy to all those who, in My opinion, qualify for such. In practice this means that I will put My hand over you shielding you, as we read in verse 22.
