Why did Moshe and Aharon fall on their faces?
Ramban: When they saw that the people were about to implement their plan to appoint a leader and return to Egypt, they fell on their faces before them 1 to plead with them to retract.
R. Bachye: They fell on their faces out of embarrassment at the public Chilul Hashem ? when the people clamored to return to Egypt ? after Hashem had told them ?Lo Sosifun Lashuv ba?Derech ha?Zeh Od?, 2 and from the fact that the entire congregation accepted the words of the ten spies and not of Yehoshua and Calev
Seforno: When they saw that the people's sin had reached a point of no return, they fell on their faces out of sheer helplessness. 3
Ta'anis 14b: In order to Daven on behalf of Yisrael.
Ramban: As in Shmuel 1, 20:41 and in Bereishis 50:19.
Seforno: Like the Sanhedrin in front of Yanai ha'Melech - See in Sanhedrin, 19b.
