When One is Humble, Hashem Expands His Wisdom:
Sefer Ohr L’Shomayim writes that the word “vayakar” symbolizes someone who is humble and considers himself small and insignificant. Such a person does not want to take any benefit or pleasure from this world, but Hashem rewards him by granting him all that he needs to serve Him properly. Hashem turns his “vayakar” into “vayikroh”, which symbolizes pleasure (as in Yeshaya 58:13).
