In short

Afar is dirt or soil, the general word, and the one that can grow things. Eifer is ashes, what fire leaves, and it grows nothing. Avak is dust, fine powder produced by pulverizing rather than by burning. Deshen is a narrower word for ashes, and the authorities differ over which ashes it names: for Rabbi Eliezer Lipman Lichtenstein it is what is burnt while fire still glows inside it, for Rabbi Yehuda Leib Shapira-Frankfurter the ashes of the avodah in the Mikdash, and for Rabbi Pappenheim only animal ash, named for the fat left in it. Since what separates afar from eifer is fertility, it is significant that the Torah calls the ashes of the Parah Adumah afar and not eifer.

Distinctions

Afar (עפר)

Dirt, soil. The word of Hashem's promise to Avraham that his descendants would be as the afar of the earth (Bereishis 13:16). Whether afar is narrowly "soil" or broadly "dirt" is a machlokes at Chullin 88b over covering the blood of a slaughtered chayah or bird (Vayikra 17:13): Beis Shammai holds only literal soil may be used, Beis Hillel that ashes serve as well, and the halachah follows Beis Hillel, which treats afar as the general term. Shabbos 18a and Rashi to Taanis 15a likewise imply that afar and eifer are synonyms, or at least interchangeable in some contexts.

  • The Zohar (Vayishlach 170a) sets the real line: afar is the crucible from which growth comes, while eifer and avak, what fire leaves behind, grow nothing.
  • The Zohar's own formulation treats eifer and avak as though they were perfect synonyms for burnt remnants; Rabbi Klein notes that this is a bit of an oversimplification, since although both are formed by a violent destructive process they are not the same thing, eifer being produced by burning and avak by pulverizing.
  • Afar is soil that can make things grow (Bartenura to Bava Basra 7:1).
  • Rabbeinu Efrayim ben Shimshon (to Bereishis 18:27): afar is cold and wet, eifer hot and dry.
  • Rabbi Moshe Shapiro draws the lesson of Bamidbar 19:17, where the Torah calls the ashes of the Parah Adumah afar: what looks like the residue of destruction can sometimes become the seed of renewal, which is exactly the point for one purified from tumas meis.
  • On the root, in Rabbi Pappenheim's system afar cannot be related to the biliteral פ-ר, because for him a two-letter root joins only HEI, ALEPH, MEM, NUN, TAV, YUD or VAV to become triliteral, and afar opens with an AYIN.
  • Others who work with two-letter roots do connect them: Rabbi Yaakov Tzvi Mecklenburg, since afar is indispensable to growing pri; and Rabbi Aharon Marcus (Barzilai), who traces both afar and eifer to פ-ר, and elsewhere (Keses HaSofer) reads afar as a fusion of ע-ף, "flying," with פ-ר.

Eifer (אפר)

Ashes, the product of burning. Rabbi Pappenheim traces it to the biliteral פ-ר, "breaking a thing down into smaller components," so eifer is matter reduced to particles by fire. From the same root he derives peirurim (crumbs), parur (a pot for crumbs and small grains), pur (the box for drawing lots, shaped like a parur), pri (fruit, a microcosm of the tree it comes from), par and parah (cattle kept for breeding), pe'er and tiferes (a beauty that resolves into many aspects), hafarah (dissolving a vow), primah (tearing a garment into shreds), and tefirah (sewing, which repairs what primah did).

The Netziv reads Avraham's afar va'eifer (Bereishis 18:27) as a double disclaimer before tefillah: some tefillos are answered in the merit of righteous forebears (Rashi to Bereishis 25:21) and some in the merit of righteous descendants (Bereishis Rabbah 29:5). Having neither, Avraham prefaced his tefillah by appealing directly to Hashem's mercy. He called himself afar because dirt has no useful past, as his own father Terach was an idolater, and eifer because ashes have no fruitful future, since, as far as Avraham could tell, he was not destined to father righteous descendants, Yitzchak not yet having been born.

Avak (אבק)

Fine dust, produced by pulverizing.

  • Rabbi Pappenheim: afar is run-of-the-mill dirt, avak is finer powder.
  • Rabbi Moshe Shapiro: avak is matter rubbed down to its core particles, light enough to be carried on the wind, and it is always the product of a struggle; the avak of Yaakov's wrestling with the angel rose to the Kisei HaKavod (Chullin 91a). Chazal's avak compounds work in this spirit, brushing the edge of a prohibition without technically crossing it: avak lashon hara (Bava Basra 165a), avak ribbis (Temurah 6b), avak sheviis (Succah 40b), avak avodah zarah (Tosefta Avodah Zarah 1:3).
  • Rabbi Yehuda Leib Edel proposes that since ALEPH and CHES are sometimes interchangeable, avak may be related to chavak/chibbuk, a hug, since such particles are so small and insignificant on their own that one meets them only clinging to, or "hugging," something else; and Rashi (to Bereishis 32:25) describes that same wrestling as chovek, a hugging.

Deshen (דשן)

A second word for ashes.

  • Rabbi Shlomo Aharon Wertheimer cites Rabbi Eliezer Lipman Lichtenstein (Shem Olam): deshen is what is burnt while fire still glows inside it, like an ember, while eifer is burnt through with no fire left.
  • Rabbi Yehuda Leib Shapira-Frankfurter: eifer is ordinary ash and deshen is reserved for the ashes of the avodah in the Mikdash.
  • Rabbi Pappenheim: "ashes" is only the secondary sense of deshen, whose primary sense is fat (Devarim 31:20; Tehillim 63:6; Mishlei 15:30); ashes of burnt animals are called deshen for the residual fat in them, so on his view deshen is only animal ash, while burnt flora yields eifer alone; fruit and vegetable oils, on his account, are deshe (Bereishis 1:11). He connects deshe and both senses of deshen to the biliteral ד-ש.

Radak on these roots

Sefer HaShorashim

א-ב-ק

Fine dust; spices ground fine, אַבְקַת רוֹכֵל; and of two men striving together, raising dust with their feet.

The fine dust

אָבָק וְעָפָר (Devarim 28:24), dust and earth, and וּפִרְחָם כָּאָבָק יַּעֲלֶה (Yeshayahu 5:24), and their blossom shall go up like dust. Fine earth, Radak says, is called אבק.

Against Ibn Ezra on the pointing

Radak says כָּאָבָק of Yeshayahu 5:24 is wholly with kamatz and is not in the construct, against what the sage Rabbi Avraham Ibn Ezra wrote there, and that Ibn Ezra confused it with כְּאָבָק דַּק (Yeshayahu 29:5), like fine dust, which in some books has the alef with sheva and patach and is in the construct; כאבק there is said of fine things, since it does not mean earth alone.

What the Mesorah notes

In most books, Radak says, that word too has a kamatz under the alef but the kaf with sheva, and the Mesorah notes on it לית, that it is unique. Radak found another note, on וְהָיָה לְאָבָק (Shemos 9:9), and it shall become dust, which says כל אבקא קמץ, every אבקא has a kamatz; and it forgot, he says, וְעָנָן אֲבַק רַגְלָיו (Nachum 1:3), and the cloud is the dust of His feet, unless perhaps it reckoned the word together with its prefixed letter.

Spices, and raising dust

Spices ground fine are called so too: מִכֹּל אַבְקַת רוֹכֵל (Shir HaShirim 3:6), of all the powders of the merchant. And וַיֵּאָבֵק אִישׁ עִמּוֹ (Bereishis 32:25), and a man raised dust with him, means that they raised dust with their feet as each strove with the other.

אָבָק וְעָפָר (דברים כח, כד), וּפִרְחָם כָּאָבָק יַּֽעֲלֶה (ישעיה ה, כד), כולו קמוץ ואיננו סמוך כאשר כתב (שם) החכם רבי אברהם אבן עזרא, והוא טעה בין זה ובין כְּאָבָק דַּק (ישעיה כט, ה), הנמצא במקצת ספרים האל"ף בשוא ופתח והוא סמוך, ופירוש כאבק הדברים הדקים, כי אין רצונו לומר עפר לבדו. וברוב הספרים גם הוא קמץ האל"ף אבל הכ"ף בשוא כְּאָבָק דק, ומסורת עליו לית. ומסרה אחרת מצאתי על וְהָיָה לְאָבָק (שמות ט, ט) כל אבקא קמץ, והנה שכח וְעָנָן אֲבַק רַגְלָֽיו (נחום א, ג), אולי כללו עם אות השמוש, העפר הדק יקרא אבק, וכן הסמים השחוקים הדק, מִכֹּל אַבְקַת רוֹכֵֽל (שיר השירים ג, ו). והנפעל ממנו וַיֵּֽאָבֵק אִישׁ עִמּוֹ (בראשית לב, כה), כלומר העלו אבק ברגליהם בהתחזקם זה עם זה.

א-פ-ר

Ash; אֲפֵר, a veil, its letters turned about from the פאר of headgear; and Ofir, a man's name given to his place, one of the places of gold.

Ash

וְאָֽנֹכִי עָפָר וָאֵֽפֶר (Bereishis 18:27), and I am dust and ash: pointed with five dots, a tzeirei and a segol, its sense is דשן, ash.

בָּאֲפֵר, a veil

וַיִּתְחַפֵּשׂ בָּֽאֲפֵר (Melachim I 20:38), he disguised himself בצעיף, with a veil; the word has the letters of the פאר of וְאֶת־פַּֽאֲרֵי הַמִּגְבָּעֹת (Shemos 39:28), and the headgear of the caps, turned about.

Ofir, where the gold is

וְאֶת־ אוֹפִר וְאֶת־חֲוִילָה (Bereishis 10:29), Ofir and Chavilah, are men's names, Radak says, and their places were called after them. They are the places of the gold, as it says, אֵת כָּל־אֶרֶץ הַֽחֲוִילָה אֲשֶׁר־שָׁם הַזָּהָֽב (Bereishis 2:11), all the land of Chavilah where the gold is, and so it is written, זָהָב מֵֽאוֹפִיר (Melachim I 10:11), gold from Ofir. In וּבְצוּר נְחָלִים אוֹפִֽיר (Iyov 22:24), and Ofir among the rocks of the streams, אוֹפִיר means the gold of Ofir.

וְאָֽנֹכִי עָפָר וָאֵֽפֶר (בראשית יח, כז), בחמש נקדות ענינו דשן. וַיִּתְחַפֵּשׂ בָּֽאֲפֵר (מלכים א' כ, לח), בצעיף, והוא הפוך מן וְאֶת־פַּֽאֲרֵי הַמִּגְבָּעֹת (שמות לט, כח). וְאֶת־אוֹפִר וְאֶת־חֲוִילָה (בראשית י, כט), שמות בני אדם ונקראו שמות מקומם על שמם, והם מקומות הזהב, כאשר אמר אֵת כָּל־אֶרֶץ הַֽחֲוִילָה אֲשֶׁר־שָׁם הַזָּהָֽב (בראשית ב, יא), וכן כתוב זָהָב מֵֽאוֹפִיר (מלכים א' י, יא), וּבְצוּר נְחָלִים אוֹפִֽיר (איוב כב, כד), פירושו זהב אופיר.

ד-ש-ן

To be fat and rich, and to make fat; the noun דֶּשֶׁן is fatness. In another sense דֶּשֶׁן is ash, and the verb is to clear away the ash, or to turn a thing to ash.

Fat and flourishing

וְאָכַל וְשָׂבַע וְדָשֵׁן (Devarim 31:20), and he will eat and be full and grow fat, he marks as a verb, and וְהָיָה דָשֵׁן וְשָׁמֵן (Yeshayahu 30:23), and it will be rich and fat, as an adjective; so too דְּשֵׁנִים וְרַֽעֲנַנִּים יִהְיֽוּ (Tehillim 92:15), they will be full of sap and fresh. The noun is in וְתִתְעַנַּג בַּדֶּשֶׁן נַפְשְׁכֶֽם (Yeshayahu 55:2), and your soul shall delight in fatness.

Making fat

דִּשַּׁנְתָּ בַשֶּׁמֶן רֹאשִׁי (Tehillim 23:5), You have made my head rich with oil, and שְׁמוּעָה טוֹבָה תְּדַשֶּׁן ־עָֽצֶם (Mishlei 15:30), good news puts fat on the bone. Where the doer is not named, נֶֽפֶשׁ־בְּרָכָה תְדֻשָּׁן (Mishlei 11:25), a soul of blessing will be made fat, and וַֽעֲפָרָם מֵחֵלֶב יְדֻשָּֽׁן (Yeshayahu 34:7), their dust will be made fat with fat.

דֶּשֶׁן as ash

In another sense, אֶל־שֶׁפֶךְ הַדֶּשֶׁן (Vayikra 4:12), to the place where the דֶּשֶׁן is poured out, pointed with six points, is the ash, and so וְכָל־הָעֵמֶק הַפְּגָרִים וְהַדֶּשֶׁן (Yirmiyahu 31:39 in his edition), and all the valley of the corpses and of the ash. That is the place where the ash was poured out, which lay outside Yerushalayim, and the pasuk says that place will be added to the city in time to come: the whole valley will be an addition to the city, and all the fields up to Nachal Kidron.

Whether Yonasan rendered the word

Targum Yonasan renders וְכָל־הָעֵמֶק הַפְּגָרִים, and all the valley of the corpses, as the plain where the corpses of the camp of Ashur fell. Radak says Yonasan either did not render וְהַדֶּשֶׁן, and the ash, at all, or rendered it by משרית אתורא, the camp of Ashur, since they were fat and rich, as it says of him וּמִשְׁמַן בְּשָׂרוֹ יֵרָזֶֽה (Yeshayahu 17:4), and the fat of his flesh will grow lean.

Clearing the ash away

וְדִשְּׁנוּ אֶת־הַמִּזְבֵּחַ (Bamidbar 4:13), which Radak glosses יסירו דשנו, they shall take away its ash, and וְעָשִׂיתָ סִּֽירֹתָיו לְדַשְּׁנוֹ (Shemos 27:3), and you shall make its pots for clearing away its ash. וְעוֹלָתְךָ יְדַשְּׁנֶה סֶֽלָה (Tehillim 20:4), and your burnt offering He will make ash, selah, he reads as ישימה דשן, He will turn it to ash: that is, He will send His fire down from heaven to consume it and to accept it with favour.

וְאָכַל וְשָׂבַע וְדָשֵׁן (דברים לא, כ), פועל עובר וְהָיָה דָשֵׁן וְשָׁמֵן (ישעיה ל, כג), תאר, דְּשֵׁנִים וְרַֽעֲנַנִּים יִהְיֽוּ (תהלים צב, טו), וַיִּֽשְׁתַּֽחֲווּ כָּֽל־דִּשְׁנֵי־אֶרֶץ (תהלים כב, ל). והשם וְתִתְעַנַּג בַּדֶּשֶׁן נַפְשְׁכֶֽם (ישעיה נה, ב), בשש נקודות, הֶֽחֳדַלְתִּי אֶת־דִּשְׁנִי (שופטים ט, ט), כבר זכרנו דקדוק החדלתי בחלק הדקדוק במקומו. והכבד [פִּעֵל] דִּשַּׁנְתָּ בַשֶּׁמֶן רֹאשִׁי (תהלים כג, ה), שְׁמוּעָה טוֹבָה תְּדַשֶּׁן־עָֽצֶם (משלי טו, ל). ושלא נזכר פועלו ממנו [פֻּעַל] נֶֽפֶשׁ־בְּרָכָה תְדֻשָּׁן (משלי יא, כה), וַֽעֲפָרָם מֵחֵלֶב יְדֻשָּֽׁן (ישעיה לד, ז). ומלה מורכבת מהנפעל והתפעל הֻדַּשְׁנָה מֵחֵלֶב (ישעיה לד, ו). וענין אחר אֶל־שֶׁפֶךְ הַדֶּשֶׁן (ויקרא ד, יב), בשש נקודות והוא האפר, וְכָל־הָעֵמֶק הַפְּגָרִים וְהַדֶּשֶׁן (ירמיה לא, לט). פירוש מקום שפך הדשן שהיה חוץ לירושלים אומר שיהיה אותו המקום נוסף בעיר לעתיד. ופירוש וְכָל־הָעֵמֶק הַפְּגָרִים תרגם יונתן וְכָל מֵישְׁרָא אֲתַר דִנְפָלוּ תַמָן פִּגְרֵי מַשִׁרְיַת אַתּוּרָאָה. רצה לומר כי כל אותו העמק יהיה תוספת העיר וכל השדמות עד נחל קדרון. והנה לא תרגם והדשן או תרגם אותו משרית אתורא לפי שהיו דשנים ושמנים כמו שנאמר עליו וּמִשְׁמַן בְּשָׂרוֹ יֵרָזֶֽה (ישעיה יז, ד). והפעל הכבד ממנו [פִּעֵל] וְדִשְּׁנוּ אֶת־הַמִּזְבֵּחַ (במדבר ד, יג), יסירו דשנו, וְעָשִׂיתָ סִּֽירֹתָיו לְדַשְּׁנוֹ (שמות כז, ג). וְעוֹלָתְךָ יְדַשְּׁנֶה סֶֽלָה (תהלים כ, ד) הה"א נוסף כה"א וָאֶקְרָאֶה לְךָ (שמואל א' כד, טו). ופירוש ישימה דשן, כלומר שיוריד אשו מן השמים לאכלה ולקבלה ברצון.

ע-פ-ר

Dust and anything fine; one in sense with אֲדָמָה, ground, אֶרֶץ, earth, תֵּבֵל, world, differing a little; עוֹפֶרֶת, lead, gaining in dust; עֹפֶר, a young hart or deer.

Dust, and the dust of gold

עָפָר מִן־הָאֲדָמָה (Bereishis 2:7), dust from the ground; עַד אֲשֶׁר־דַּק לְעָפָר (Devarim 9:21), until it was ground fine as dust. וְעַפְרֹת זָהָב לֽוֹ (Iyov 28:6), and it has dusts of gold, means the dusts out of which the gold is taken; or else the ground gold is itself called dust, as it is written וָֽאַשְׁלִךְ אֶת־ עֲפָרוֹ (Devarim 9:21), and I cast away its dust, and as Chazal said (Avodah Zarah 44a). Ash too is called dust, מֵֽעֲפַר שְׂרֵפַת הַֽחַטָּאת (Bamidbar 19:17), from the dust of the burning of the chatas.

עפר, אדמה, ארץ, תבל

The four are of one sense and are set beside one another, as עַפְרוֹת תֵּבֵל, the dusts of the world, אַדְמַת־עָפָר (Daniel 12:2), the ground of dust, and עַל־ עֲפַר ־אֶרֶץ (Amos 2:7), on the dust of the earth; yet Radak says there is a small difference between them. עפר is mostly said of what is fine, and so is אדמה, as וַֽאֲדָמָה עַל־רֹאשֽׁוֹ (Shmuel I 4:12), and earth upon his head, though אדמה is seldom said of the fine. Between ארץ and תבל too there is a small difference: ארץ takes in the whole, settled land and wilderness together, and תבל takes in the settled part only.

Fine things called dust

Radak says fine things are named by dust: וַיָּדֶק לְעָפָר (Melachim II 23:6), he ground it to dust, and וְנָשָׂא אֶת־ עֲפָרָם (Melachim II 23:4), he carried away their dust. The heavy verb taken from it is וְעִפַּר בֶּעָפָֽר (Shmuel II 16:13), and he dusted with dust.

עוֹפֶרֶת and עֹפֶר

צָֽלֲלוּ כַּֽעוֹפֶרֶת (Shemos 15:10), they sank like lead, is the metal אבר, as the Targum has it. It is rightly named על שם האפר, after the ash, since dust eats away all metals and lessens them while they lie in it, but lead gains in dust. And לְעֹפֶר הָֽאַיָּלִים (Shir HaShirim 2:9), to a young hart, and כִּשְׁנֵי עֳפָרִים (Shir HaShirim 4:5), like two young ones: the עֹפֶר is the young of the hart or of the deer.

עָפָר מִן־הָאֲדָמָה (בראשית ב, ז), בַּרְזֶל מֵֽעָפָר יֻקָּח (איוב כח, ב), עַד אֲשֶׁר־דַּק לְעָפָר (דברים ט, כא), וָֽאַשְׁלִךְ אֶת־עֲפָרוֹ (שם), וְרֹאשׁ עַפְרוֹת תֵּבֵֽל (משלי ח, כו), וְעַפְרֹת זָהָב לֽוֹ (איוב כח, ו), פירוש העפרות שיוקח מהם הזהב. או יקרא הזהב השחוק עפר כמו שכתוב ואשליך את עפרו, כמו שאמרו רבותינו ז"ל (עבודה זרה מד, ע"א). וכן האפר נקרא עפר מֵֽעֲפַר שְׂרֵפַת הַֽחַטָּאת (במדבר יט, יז). עָפָר, אֲדָמָה, אֶרֶץ, תֵּבֵל, ארבעתם ענין אחר ונסמכו זה לזה כמו עַפְרוֹת תֵּבֵל, אַדְמַת־עָפָר (דניאל יב, ב), עַל־עֲפַר־אֶרֶץ (עמוס ב, ז), ואף על פי כן יש הפרש ביניהם מעט, כי עפר יקרא הדק ברוב וכן אדמה כמו שאמר וַֽאֲדָמָה עַל־רֹאשֽׁוֹ (שמואל א' ד, יב) ומעט נזכרה האדמה על הדק. וארץ ותבל יש ביניהם הפרש מעט כי ארץ היא כלל הכל ישוב ומדבר, ותבל כלל על הישוב. וכן הדברים הדקים יכונו בעפר כמו שאמר וַיָּדֶק לְעָפָר (מלכים ב' כג, ו), וְנָשָׂא אֶת־עֲפָרָם (מלכים ב' כג, ד), וַיַּשְׁלֵךְ אֶת־עֲפָרָהּ (מלכים ב' כג, ו). והפעל הכבד [פִּעֵל] הנלקח ממנו וְעִפַּר בֶּעָפָֽר (שמואל ב' טז, יג). [מֵאֵשׁ תַּם] עֹפָרֶת (ירמיה ו, כט), צָֽלֲלוּ כַּֽעוֹפֶרֶת (שמות טו, י), הוא האבר כתרגומו. ואמת שנקרא כן על שם האפר כי כל המתכות יאכלם העפר ויפחתו בהיותם בו אבל העופרת הוסיף בעפר. לְעֹפֶר הָֽאַיָּלִים (שיר השירים ב, ט), כִּשְׁנֵי עֳפָרִים (שיר השירים ד, ה), הוא ילד האיל או הצבי.
