Sry, wont give you a dvar Torah, you gotta do some work yourself 🙂
lest you give the speech in my name. However will put in my two cents,
perhaps you can build on that,(I had no luck so far)
In Bereishis it says after HB”H created Chavah, * “al kein yazoiv ish
es aviv vi’es Imoy V’dovak b’ishto v’hoyu l’basar Echad.
When a man leaves the shadow of his parents he is able to cleave to his
wife & in turn becoming one, creating a family. This is not to say he leaves the
wonderful things he has learned from them, or respect them any less c”v.
only that in leaving his parents house, lets him rise to be a man himself,
leaving the protection & financial support he goes out to stand
on his own two feet B”H.
This concept we can relate to this weeks parsha of Lech, Le’cho.
HB”H Tells Avram Go! Leave your home, your land, which you are familiar with,
and i will lead the way and guide you. Lecha, it’s for your benefit having to
leave your father home, for many blessing & success await you after leaving
here andstarting anew on your own. this is what a Chosson does when he gets
married. He leaves his parents home & starts his own B”H, as the Torah states
in breishis* this concept I believe is repeated in Lech, Go Chosson, leave,
L’cho. go for your own benefit, taking the good things you saw by your parents
and grandparents L’cho with you & build on that.
(this is my own p’shat) hope it helps! Mazel Tov!
