בראשית, פרק י״ז, פסוק ז׳

The Creator of all worlds chooses to narrow His divine focus, forging a deeply personal and unique covenant with a single individual and his family. Following ten generations of moral decay since the days of Noah—a period during which God hoped to establish a bond with all of humanity—He now exclusively selects Abraham. He promises him an eternal bond that will never be broken [ביאור יש״ר, ביאור שטיינזלץ]. This agreement is far more than a private promise; it serves as the very foundation upon which the existence of the entire world relies [מלבי״ם]. God commits to upholding and carrying this covenant forward despite any difficulties. The journey of Abraham's descendants will be fraught with historical struggles, yet God pledges to guide, educate, and refine them until they achieve their ultimate purpose [רש״ר הירש, העמק דבר].

The essence of this entire relationship is defined by God becoming their personal deity [רש״י]. The primary approach among commentators is that this signifies absolute, direct, and individual providence, free from any intermediaries or celestial representatives of other nations. God Himself acts as the direct leader and patron of the people [ספורנו, אלשיך]. Because His actions are everlasting, this direct link to the Eternal grants the nation of Israel an eternal existence as a community [ספורנו]. This unique protection shielded the Patriarchs and select individuals even before the giving of the Torah, and it continues to preserve the nation throughout their exile, even when surrounded by enemies [מלבי״ם, העמק דבר]. Furthermore, this bond holds the seeds for all future blessings, including miracles, prophecy, the giving of the Torah, and their destiny as a treasured people [ביאור יש״ר].

The ultimate peak of this direct providence is fully realized when the people enter the land of Israel and observe the commandments of circumcision and the Sabbath [אלשיך]. Circumcision itself acts to remove spiritual barriers, preventing negative judgments and allowing for a profound attachment to God [צרור המור]. However, this divine promise does not extend to all of Abraham's biological children; it is specifically focused on the descendants of Jacob [רד״ק]. The continuation of this legacy carries a dual requirement. Spiritually, it applies only to those who follow in Abraham's footsteps and keep the ways of God [קונטרס חיבה יתירה]. Physically and legally, the lineage must be absolutely clear. The Divine Presence rests only upon a well-defined family line. This principle establishes the rule requiring a woman to wait three months between marriages to ensure the father's identity is certain, and it also excludes offspring born to foreign women from the natural continuation of the lineage. Ultimately, the emphasis on future generations highlights the vital importance of having children. Avoiding this responsibility causes the departure of the Divine Presence, which relies on the arrival of new generations to continue dwelling within the world [תורה תמימה].
