GEN881 If one has as good eye, an humble temperament, and a lowly spirit, he is of the disciples of Abraham our Father. Pirkei Avot V:2   … the Almighty promised Abraham that at last Sarah would bear him a son. The Patriarch’s only reply was, “O that Ishmael might live before thee!”  In his humility, Abraham was ready to be satisfied with whatever he had.   One Sage learned directly from Abraham.   At the wedding-feast for his son, Rabbi Gamaliel II personally poured cups of wine for his colleagues.   He offered a cup to R. Eli’ezer, and that Sage would not take it; he offered it to R. Joshua, and that Sage accepted it.   Said R. Eli’ezer, “What is this, Joshua? Is it right that we should sit reclining and Gamaliel the son of Rabbi [Judah haNasi] should stand and serve us?”  Replied R. Joshua, “Let him serve. Abraham, the world’s most outstanding citizen, attended upon ministering angels.  Think you they looked like ministering angels to him? They appeared to him as nothing but idolatrous Arabs. Then shall we not surely allow Gamaliel the son of Rabbi to serve us?” Said R. Tzadok to them, “You have overlooked the glory of the Omnipresent [God] and concerned yourselves with the glory of a flesh-and-blood mortal. The Holy, Blessed One, who spoke and the world became, makes winds blow, clouds rise, rain fall, and plants sprout, and thus He sets a meal-table for every single person. Shall then Gamaliel the son of Rabbi not attend upon us?” Talmud Kiddushin 32, Midrash Sifre, Deuteronomy §38.   SINAI3 202
