We find an intriguing exploration of just that in Bereshit Rabbah 48, a section of the ancient midrashic collection on the book of Genesis. It all stems from Genesis 18:5, where Abraham welcomes the three angels (disguised as travelers, of course!) with the invitation, "And I will take a piece of bread, and you will sustain your heart, then depart, inasmuch as you have passed by your servant. They said: Do so, as you have said."
What's so special about bread? Rabbi Yitzḥak points out a fascinating pattern: Scripture consistently links bread to the sustenance of the heart – not just physically, but perhaps spiritually as well. He finds evidence across the Tanakh (the Hebrew Bible). In the Torah itself, we have Abraham’s invitation. Then, in the Prophets, Judges 19:5 echoes the sentiment: "Sustain your heart with a piece of bread." And finally, in the Writings, Psalms 104:15 declares, "And bread sustains man’s heart." Pretty convincing. But the Rabbis don't stop there. Rav Aḥa dives into the nuances of the Hebrew. He notes that the verse doesn't say "levavkhem" (לְבָבְכֶם), which usually indicates both the good and evil inclinations within the heart, but rather "libekhem" (לִבְּכֶם), with only one bet (ב). Why does this matter? Well, according to Rav Aḥa, this subtle difference teaches us that angels don't have an evil inclination, a yetzer hara (יֵצֶר הַרַע).
This idea resonates with Rabbi Ḥiyya's interpretation of Psalms 48:14. He points out a similar grammatical distinction, arguing it foreshadows a time – perhaps the Messianic era – when the evil inclination will no longer have dominion. It is worth noting that the word "heart" can be spelled with one bet (lev, לב) or two (levav, לבב). When it is spelled with two bets it means to include both man’s good inclination and his evil inclination (Mishna Berachot 9:5).
Then, Rabbi Yehoshua offers a beautiful interpretation of the phrase "al ken" (עַל כֵּן), "inasmuch as you have passed by your servant." He suggests that Abraham is saying something profound: From the very moment of creation, these angels were destined to visit him. He connects "ken" to the repeated phrase "vayehi khen" (וַיְהִי כֵן), "and it was so," which appears throughout the creation narrative. It's as if Abraham is acknowledging a divine plan, a preordained encounter.
Interestingly, this idea of preordained events echoes in Pharaoh’s words to Moses in Exodus 10:10, "So [khen], may the Lord be with you." There, too, Pharaoh, perhaps grudgingly, acknowledges the possibility that the Exodus was destined to happen.
Finally, the angels' response, "Do [ta’aseh] so, as you have said," gets another layer of meaning. The midrash suggests they're saying that eating and drinking don't apply to them, but that Abraham, for whom these things do apply, should perform the act of hospitality. And it's not just about this meal! The angels wish that Abraham merit to prepare another feast for his offspring, alluding to the celebration for Isaac's weaning recorded in Genesis 21:8.
So, what can we take away from this deep dive into a single verse? It's more than just a story about hospitality. It's about the power of simple acts, the constant struggle within ourselves, and the possibility of a future free from the yetzer hara. And it all starts with… a piece of bread. Who knew so much could be packed into such a small offering?
