Avraham's Bread Without Waste

בשם מו"ז ז"ל על מ"ש חז"ל מן התורה ונביאים וכתובים פתא סעדתא דליבא מהו באו להשמיענו רק לומר שיש בו גם מזון רוחני אל הלב.

In the name of my grandfather, of blessed memory: regarding what Chazal said — from the Torah, the Prophets, and the Writings [we derive] that bread is a support for the heart (sa'ada d'liba) — what did they come to teach us? Only to say that there is in it [bread] also spiritual nourishment for the heart.

Citing his grandfather (the Chiddushei HaRim), the Sefas Emes asks why Chazal needed three Scriptural sources to prove the obvious fact that bread sustains a person; the answer is that they meant a deeper point — bread feeds not only the body but also the heart, the soul.

ולכן כתב רש"י סמיך לזה לבכם לבבכם אין כתיב שאין יצה"ר שולט במלאכים א"כ הפת סועד לב הפנימי מחלק היצ"ט כו'.

And therefore Rashi wrote nearby [on the angels visiting Avraham]: it says "your heart" (libchem, single-letter) and not "levavchem" (double-letter), for the yetzer hara has no dominion over the angels — so the bread sustains the inner heart, from the portion of the yetzer tov (good inclination).

Rashi notes that regarding the angels the Torah uses "libchem" (one bais) rather than "levavchem" (two), because angels lack a yetzer hara and so have only a single "heart." This proves bread's nourishment reaches the inner, good heart — the side of the yetzer tov — not merely the physical appetite.

והענין הוא כי האוכל צריך בירור ולכן הוא מזון לגוף ולנפש כל אחד מקבל חלק שלו.

And the matter is this: food requires clarification (birur), and therefore it is nourishment for the body and for the soul — each one receives its portion.

Ordinary food is a mixture that must be sorted (birur): the coarse part feeds the body, while the refined, holy part nourishes the soul — each draws its own share.

ולחמו של אברהם אבינו לא הי' צריך בירור ולא הי' בו פסולת [כמ"ש לחמו כו' נאמנים היינו בלי פסולת] כמו בשבת שנקרא סעודתא דמיהמנותא שאין בו פסולת וא"צ בירור ונמשך אחר השורש ולכן גם הנשמה יתירה ניזונות מסעודות שבת.

But the bread of Avraham Avinu did not require clarification and had no waste (pesoles) in it — [as it is written, "his bread... is faithful (ne'emanim)," meaning without waste] — like Shabbos, which is called "the meal of faith" (se'udasa d'mehemnusa), in which there is no waste and which requires no clarification, and which is drawn after the root; and therefore even the neshamah yeseirah (additional soul) is nourished from the Shabbos meals.

Avraham's bread was so pure and holy that it needed no birur and contained no waste at all — comparable to the Shabbos meals, the "se'udasa d'mehemnusa," which are wholly refined, need no sifting, and flow directly from their holy root. Because such food is entirely spiritual, even the extra "Shabbos soul" can be fed by it.

וכמו כן המלאכים סעדו מלחמו של אאע"ה:

And likewise the angels were nourished from the bread of Avraham Avinu, peace be upon him.

Since Avraham's bread was pure spiritual nourishment with no physical waste, even the angels — who have no body to feed — could partake of it.

Summary: Quoting the Chiddushei HaRim, the Sefas Emes explains that Chazal's three sources for "bread sustains the heart" teach that bread carries spiritual nourishment for the soul, not just the body — supported by Rashi's note that angels, lacking a yetzer hara, have a single "heart." Ordinary food is mixed and must undergo birur, body and soul each taking their portion; but Avraham's bread, like the Shabbos "meal of faith," was wholly pure, free of waste, drawn straight from its root — which is why even the neshamah yeseirah and the bodiless angels could be nourished by it.
