Hearts Of Wisdom

The Torah describes the woman whom spun the wool's hair for the covering of the mishkan as נשא לבן בחכמה.  The Torah uses the expression נשא לבן or נדבה רוחן.  What is this additional expression of חכמת לב?  Rav Hirsch says that the other descriptions refer to the willingness to give (נדבה רוחן) or to give one's entire self over(נשא לבן.)  However, חכמת לב refers to that their willingness to give was guided by their brain.  Everyone rushed to donate the beautiful materials but forgot about the basic materials needed for the coverings.  However, the woman that were חכמי לב realized that this was the most important.  "This was the real actual אהל and the making of an אהל is where the quintessence womanhood is concentrated, so in that in this they displayed both careful thought and their sense of true womanhood, their חכמה." 
The woman that were חכמי לב recognized the correct roll of woman in society and reflected it through their work on the mishkan.
