Greeting guests and more in Vayera

For this week's parsha, I posted a blog on Times of Israel  that looks at what we learn from Avraham's actions in preparing for guests.  It contains a link to Rabbi Frand's Lesson #1 In Hospitality: Don’t Let Your Guests Feel Inferior.

For what my grandfather wrote about Sarah's laughter in the parsha,  and a brief insight into Lot's wife turning into salt see http://kallahmagazine.blogspot.com/2015/10/sarahs-internal-laughter.html

For how Rivka is introduced see this explanation.
