The value of having guests[1]
ויאמר אדנ”י אם נא מצאתי חן בעינך אל נא תעבור מעל עבדך
[Avraham] said: “My Lord, if I have found grace in Your eyes, please[2] do not pass by from Your servant”[3]
On a hot day, Avraham was waiting outside his tent for prospective guests[4]. Hashem appeared to him in a vision, although what the vision consisted of we aren’t told[5]. Soon after, three Angels in the garb of Arab nomads[6] approached Avraham’s tent. Avraham, not wanting to pass up the opportunity to greet these potential guests, politely asked Hashem for permission to be excused[7]. The gemarra[8] learns from here that greater is taking care of guests than greeting the Divine presence. Since Avraham interrupted his vision of Hashem to greet the guests, we see it was of greater value[9].
