Avraham is committed to spreading the word of Hashem to the world & having hachnasas orchim. Avraham plants the Eishel Tree, and then right after that story comes the Akeida. Whats the Eishel tree? Leafy tree, orchard, full on hotel - pleasurable for guests! Message for us? Jewish DNA is chessed and gemilus chasadim. Help them physically and also to lighten others soul burden. Hachnasas Orchim is more than tzedakah, you make the person feel welcome - like escorting them out to the door. How far do we go? ....While in a place that is comfortable, good times, plant an Eishel and give over to help another person, going all out in the most beautiful way - that kind of approach enables them to then go into an Akeida bsimcha. Lesson for all generations: A person can give to others, not just the basics, but the best of the best in Torah and Mitzvos, this is how we raise a generation of mesiras nefesh. We are ready to go all out! Serve every person coming through our eishel. Raise children around that and they will grow up ready to do whatever is needed for Torah & mitzvos. Hashem pays you back in huge, beautiful ways.
