See Beraishis 28:10, page 598:
Yakov goes forth in order to establish a Jewish home, and to achieve this he needs only the resources inherent in his own personality. Thus begins the story of Yaakov, for everything that follows revolves around the establishment of that home. Yaakov was the first to give expression to the idea that God is to be sought within the home….. The sphere in which man blossoms and thrives, the place to which he brings all that acquires and in which he acts and builds his life – that sphere is the greatest and nearest place for the revelation of God…. עיקר שכינה בתחתונים
See Beraishis 28:14 page 603:
Yaakov exhibits the first Jewish home and teaches how, without inherited wealth one can build and live a family life upheld by the blessing and dignity of work, with all its worries, troubles and griefs.
How to lead a family life, a national life, upheld by the grace of God and refined in accordance with His Will – this, mankind will learn from you (Yaakov) and from your descendants.
See Hirsch’s commentary on the Korban Pesach where RSRH explains its symbolism of the importance of family and of a community that cares for one another. (First major essay in the Hirsch Haggadah)
