Because of the winter, a lazy man does not plow; he will seek in harvest, and there will be nothing.Rabbeinu Behaye captures the spirit of each week's parshah with a verse from Mishlei, preparing us for the fundamental ideas to be discussed in the parshah.
מֵחֹרֶף עָצֵל לֹא יַחֲרשׁ יְשָׁאַל וְשָׁאַל בַּקָּצִיר וָאָיִןMishlei 20:4
He explains how the author of Mishlei, Shlomo HaMelech, sought to convey many important principles and useful life lessons, but some of the most important concepts are "זריזות" (diligence) and "עצל" (laziness).
Says the Rabbeinu Behaye, we can see these concepts across all aspects of life: running a home, caring for our bodies, spiritual matters, and Torah.
