1. Avraham’s Declaration: “Ofer va-Eifer” and Its Meaning
The Torah tells us that when Avraham pleaded with Hashem, he described himself as “like sand and like ashes”—ofer va-eifer—sand and ashes. The Gemara in Masechet Soyta discusses this verse at length, exploring the significance of Avraham’s words. The Sages explain that these two elements, sand and ashes, are later reflected in two distinct mitzvot given to Avraham’s descendants.2. The Two Mitzvot: Ofer of Sotah and Eifer of Parah Adumah
The Gemara explains that the “ofer” (sand) refers to the mitzvah of ofer sotah—the dust used in the ritual for a woman suspected of adultery. This dust was taken from the floor of the azorah&mdash>the courtyard of the Mishkan or Beit HaMikdash—and mixed into the water for the Sotah ceremony. The “eifer” (ashes) refers to the ashes of the parah adumah—the red heifer—which were used to purify those who had become impure through contact with a corpse. The Gemara also raises a question about why we don’t count the sand used for kisui hadam—covering the blood after shechitah—as one of these special mitzvot, but concludes that it does not have the same benefit or significance.3. Self-Sacrifice in These Mitzvot: Helping Others at Personal Cost
The Rebbe highlights what is unique about these two mitzvot: both demonstrate a profound level of self-sacrifice for another person. In the case of parah adumah, those involved in preparing its ashes—the kohanim—would themselves become impure in order to purify others who were tamei meis—impure from contact with a dead body. This shows a willingness to give up one’s own spiritual purity so that someone else can be cleansed. Similarly, with the sotah, Hashem allows His own holy name to be erased—something usually strictly forbidden—in order to bring peace between husband and wife. This act demonstrates how far one should go, even giving up something precious or holy, for the sake of helping another or making peace.4. Avraham’s Example: Prioritizing Others Over Spiritual Attainment
This theme is reflected in Avraham’s actions at the beginning of our parsha. When Hashem appeared to him, Avraham interrupted his encounter with the Shekhinah—the Divine Presence—to welcome guests into his home. These guests were not particularly elevated people; Chazal say they were Arabs who bowed down to the dust on their feet, which is why Avraham asked them to wash before entering—to avoid bringing any trace of avodah zarah—idol worship—into his tent. Despite their low spiritual level, Avraham was willing to set aside his own spiritual experience for their sake. He told Hashem to wait while he attended to their needs, demonstrating true selflessness.5. The Reward for Self-Sacrifice: Gaining More Than You Give Up
Interestingly, as mentioned previously, even though it seemed that Avraham was giving up by leaving Hashem’s presence, he did not actually lose out. The Shekhinah remained nearby while he tended to his guests—if anything, Hashem stayed longer than originally planned because of Avraham’s actions. This teaches us that when we sacrifice our own spiritual growth or comfort for another person’s benefit, we do not truly lose out—in fact, we often gain even more in return.6. Teaching Others: The Lesson from Tanya and Tzemach Tzedek
This idea is echoed by the Tzemach Tzedek and brought down by the Alter Rebbe at the beginning of Tanya. Sometimes when you teach someone else material you already know well, it may feel like you are not advancing your own learning as much as if you studied alone at your level. However, Tanya cites the verse “me’orei nishnei me’Hashem”—Hashem enlightens those who teach others—and explains that sometimes you can accomplish in one hour what would otherwise take a thousand hours on your own. Thus, by helping others—even if it seems like you are sacrificing your own progress—you end up gaining much more than you give up. This is a core message both from Avraham’s example and from our sages: true selflessness leads not only to helping others but also to greater personal growth and reward.
