Moshe Rabbeinu and the Small Aleph of Vayikra
Moshe Rabbeinu asks Hashem not to open Vayikra with words showing his greatness. Hashem agrees to write the aleph small, as a sign of Moshe’s humility.
Moshe Rabbeinu asked Hashem, “Why did you start a sefer Chumash with a pasuk that demonstrates my greatness by stating that You directly called to me?” Hashem responded, “I couldn’t start the verse with the word vayikar, because that implies that I just happened to talk to you.” That is the word in the Torah used in reference to Hashem talking to Bila’am. Whereupon Moshe pleaded with Hashem, “Please at least make it known to the future generations that it was difficult to me the way the Torah started Vayikra.” Hashem acquiesced and commanded that vayikra be written with a small aleph to make known that Moshe Rabbeinu would have preferred that the term vayikar be used in reference to him when starting sefer Vayikra.
