The Mitzvah of Sefiras HaOmer is formulated in two places in the Torah. In Parshas Emor, we find the requirement to count a specific number of days, while in Parshas Re'eh, we are told to count a certain number of weeks. While the total period of counting ends up being the same, there seems to be a difference between these two sources as to what unit of time is to be used. On the basis of these two different sources, Abaye is of the opinion that what we must do is mention both the day and the week during the course of our counting, and although there is a dissenting view, it is Abaye's position that has been accepted by the Rambam and by the Shulchan Aruch and that is followed today.

In a homiletic vein, it may perhaps be suggested that these two different units of time - Days and Weeks - represent two different approaches in terms of time awareness and in considering one's future along with the present actions which determine that future. A day is a unit which is representative of the short term approach. This approach emphasizes primarily the immediate future. One who considers only the upcoming day focuses on his immediate needs and solving immediate problems without necessarily considering the broader implications and the ultimate results of what he is doing. A week, on the other hand, is symbolic of the long term approach. This approach emphasizes the need to look further down the road and realize what is ahead in terms of the "Big Picture". One who considers only the week, however, examines only the ultimate implication and sometimes does not see the value of each independent action.

The Mitzvah of Sefiras HaOmer, requiring a dual awareness of both the day and the week, reminds us that we must actually be cognizant of both the short term situation and the long term situation. One must therefore consider the large perspective, looking to the future and anticipating the long term effects of his actions. But at the same time as having this sense of the long term purpose, one must realize the import of each of his actions in terms of the immediate future, understanding that each day is valuable and that short term considerations must play a role in one's actions as well. As we approach the Yom Tov of Shavuos, identified as Z'man Matan Toraseinu, we must consider both the infinite value and potential of each given moment as well as the overall long term goals which drive our actions as Jews who understand what Kabbolas HaTorah is all about.
