בראשית, פרק י״ב, פסוק ז׳

Abraham’s arrival in the land of Canaan marks a profound turning point in his relationship with God. Until this moment, his spiritual experiences outside the land were limited to a prophetic voice or messages received in dreams. Only upon entering the land does he experience a clear, full prophetic vision [אבן עזרא]. This shift occurs because the land itself is the proper and prepared environment for the Divine Presence to rest [רמב״ן, כלי יקר, העמק דבר, ביאור יש״ר, קאסוטו]. This divine appearance during a period of wandering also serves as a foreshadowing, as God will similarly reveal Himself to Jacob when he too is forced into exile and wandering [קיצור בעל הטורים].

During this revelation, God makes an absolute promise to give the land to Abraham's offspring. Previously, the assurance that he would become a great nation was conditional upon his willingness to embark on the journey, but now the promise is granted unconditionally [גור אריה, יריעות שלמה]. The guarantee is directed toward his descendants rather than Abraham himself, since a single individual cannot inherit and settle an entire country. While Abraham gains the right to walk the land freely, the actual inheritance and the displacement of the local nations will occur gradually only as his offspring multiply [רד״ק]. This promise also serves to calm Abraham's concerns as he witnesses the Canaanites actively conquering the territory. God reassures him that their dominion is strictly temporary and that the land is ultimately destined for his righteous descendants [מלבי״ם, ביאור יש״ר, קונטרס חיבה יתירה].

Promising a physical inheritance to an unborn generation raises a legal question, as property cannot typically be acquired on behalf of those who do not yet exist. However, this acquisition is made possible through the future status of the Israelites as children of God, a profound spiritual relationship that Abraham solidifies immediately afterward through his actions [אדרת אליהו].

Following the revelation, Abraham constructs an altar. The primary approach among commentators is that this structure was built as an expression of deep gratitude for the two great tidings he received: the promise of children and the promise of the land [רש״י, רד״ק]. Some note that the physical location represented the land, while the revelation itself pointed to the promise of offspring [משכיל לדוד]. Conversely, another perspective suggests that Abraham’s primary joy did not stem from the material promises of family and territory. Rather, the altar was dedicated purely to God out of a profound love for the Creator, celebrating the immense privilege of witnessing the Divine Presence [אור החיים, ביאור יש״ר, חומש קה״ת].

Regarding the altar's practical function, some maintain that it was actively used to offer thanksgiving sacrifices to God [רמב״ן, מלבי״ם]. Others argue that no sacrifices were offered at all. Instead, the altar stood as a monument and landmark, symbolizing the spiritual and national conquest of the land and its dedication to divine service [קאסוטו, The Torah]. The very act of building an altar within a Canaanite settlement indicates that Abraham had already begun to influence the local inhabitants. He taught them the principles of monotheism and secured their consent to build the structure without fearing they would repurpose it for idolatry [הכתב והקבלה]. Furthermore, the specific placement of the altar was guided by prophetic foresight. Abraham foresaw that his future descendants would stumble in a severe sin in this exact area—the sin of Achan—so he established the altar to pray for their forgiveness in advance [ברטנורא].
