בראשית, פרק כ״ג, פסוק כ׳

The purchase of the Cave of Machpelah represents more than a simple financial transaction; it is a historical milestone where Abraham establishes his first permanent hold in the Promised Land. The narrative highlights a transition from merely paying for the property to securing an eternal grip on the land. The primary approach among commentators is that the acquisition happened in two distinct stages. While the initial agreement involved the contractual and financial transfer, the final stage of practical possession was only achieved the moment Abraham actually buried Sarah in the cave [רבנו בחיי, רס״ג, אם למקרא]. This physical act of burial legally transformed the property into a formal cemetery [צפנת פענח]. Others explain that during the initial purchase, the exact purpose of the field was not explicitly defined. Only after the burial was it officially established that the site would serve as a permanent burial estate, rather than a place for housing or agriculture [העמק דבר, קונטרס חיבה יתירה].

Although the deal was made with an individual owner, the final transfer required broad public consent from the local people. This widespread approval was necessary to bypass local laws that prohibited foreigners from owning a burial estate [אלשיך, מלבי״ם], or perhaps because the field was considered public land belonging to the kingdom [פענח רזא]. Furthermore, securing the agreement of the townspeople prevented any future complaints about bringing the impurity of the dead close to their agricultural fields [חזקוני, העמק דבר]. This public approval was granted willingly and with full consent, as the local inhabitants were genuinely happy to have Abraham become a permanent resident among them [רד״ק, ספורנו].

Beyond the legal details, this purchase carries profound spiritual significance. The site is one of three locations in the land of Israel bought for full price to establish absolute, unquestionable ownership [רבנו בחיי, רס״ג]. Abraham's insistence on acquiring a permanent and expensive burial estate also served to instill faith in the surrounding nations. While the local people viewed burial as a temporary measure meant simply to dispose of a body for convenience, Abraham used this opportunity to teach them about the immortality of the soul and the future resurrection of the dead, concepts that demand a respectful and eternal resting place for the physical body [מלבי״ם]. Finally, because the local people acted generously, approved the transaction, and assisted a righteous man in securing his purchase, they were granted special honor, with their name mentioned numerous times throughout the narrative [רבנו בחיי, הדר זקנים].
