Ki Tisa - Shlishi
If Moshe Didn't Get It, Why Would We?
Moshe prayed to G-d to better understand His ways, specifically why the righteous suffer. (See Talmud Brachos 7a.) He also asked G-d to confirm that Israel was still His people. While G-d declined to reveal to Moshe all the metaphysical inner workings of the universe, He did assure Moshe that the Jews had not forfeited their position with Him. To that end, He agreed that His Presence would accompany the nation after all.
Moshe replied, "Good, because if You're not with us, we're not going!"
