שמות לד:ג פירוש: רש״י, רמב״ן, טור הארוך ורבנו בחיי

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).

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.

ואיש לא יעלה עמך, “and no man may ascend with you.” Unlike the first time around, this time the elders were no to accompany Moses even part of the way.
