The Shikkerdovid would like to come back to some basic original ideas. Toward the end of the parsha, the Torah talks about the gifts that people give to the Kohan. In Chapter 18, verse 12 the Torah says, to Give trumah of the “Best oil and best wine and first fruits of the ground (dagan). The hebrew is yizhar (oil), tirosh (wine) and then dagan (grain.
Interestingly, if you look at the second paragraph of the shma the order is reversed. The torah tell us you if you listen to Gd, you shall “gather your grain, your wine and your oil” THe order is changed. THis order makes more sense. People need to eat, then drink wine and then have oil to illuminate in order to exist. Clearly, grain is primary.
The SHikkerdovid asks therefore, why when the Torah discuss the gifts of Termuah it uses the order : oil, wine grain, however in the shma it is grain, wine oil. The Shikkerdovid would like to posit the obvious answer. When you give a gift or an offering, you are doing the best you can. You are giving to fulfill the dictate of the Torah. You do the best you can.
However, survival requires more than just the best. YOU NEED THE GRAIN FIRST AND FORMOST. The message to the Shikkerdovid is clear. Do what the Torah tells us in the order it perscribes, and Hashem will give you the things you require, in the order of necessity.
