פּירוש אויף שמות 34:3

ואיש לא יעלה עמך AND NO MAN SHALL GO UP WITH THEE — Because the first tablets were given amidst great noises and alarms and a vast assembly the “evil eye” had power over them (they did not endure) — there is no finer quality than to be unostentatious! (Midrash Tanchuma 3:9:31).

ואיש לא יעלה עמך, “and no one is to ascend with you.” On the first occasion after the revelation on Mount Sinai G-d’s instructions had been that before ascending the Mountain, Aaron Nadav and Avihu and the seventy elders were to accompany him part of the way. (Exodus 24,1) On this occasion the elders were too ashamed and kept their distance, on account of the people still being in a state of disgrace.

AND NO MAN SHALL COME UP WITH THEE. None of the elders of Israel at all should go up with you, as they had done at the first Tablets of the Law.⁵⁰¹Above, 24:9.
