Vayikra 5773 (part 1)

Why is the Alef in the word "Vayikra" written small? The Ba'al Turim explains that Moshe had wanted to write the word "Vayikar," without the Alef; this would mean that Hashem "happened" upon him in a vision rather than willingly appear to Moshe. He was humble and did not want to look like a very important person. Nonetheless, Hashem told Moshe to write the Alef, but Moshe still requested that it would be written with a small Alef.
