Kaisipang Hudyo sa Mga Awit 42:1: Akeidat Yitzchak

We find a Midrash Tanchuma on Parshat Beshalach section twenty, which states that expounding and interpreting Torah has been granted only to those who ate manna and those who live on tithes. It is clear that the meaning is that only people who do not have to worry about providing a livelihood for themselves and their families, can take out sufficient time to immerse themselves deeply in the study of Torah. Since the generation of Jews who came out of Egypt had no need to work for a living, they qualified for the task of Torah study in depth. In fact, that generation was immune from all the four impediments normal people face in their quest for G'd and His Torah.
