בראשית, פרק י״ז, פסוק ו׳

The promise made to Abraham elevates him entirely above the natural order, granting him a global and enduring influence. The assurance of extreme multiplication goes beyond a simple blessing for biological descendants, which he had already received, and introduces a supernatural level of growth [מלבי״ם, העמק דבר]. This profound blessing marks his departure from the control of astrology and natural fate, placing him under God’s direct, personal guidance as a reward for accepting circumcision [פני דוד]. Furthermore, it serves to reassure him that the physical act of circumcision will not weaken his strength; rather, it will have the exact opposite effect [מלבי״ם].

When addressing the promise that Abraham will become a father to multiple nations, commentators offer varying perspectives on who these nations are. One approach takes this literally, pointing to the different peoples that would descend from him. Since Ishmael was already born, this new promise is understood to refer to the Israelites and the descendants of Edom [רש״י, מזרחי, הטור הארוך], with some extending it to include the children of Keturah [רד״ק]. However, this raises a question: how could the Edomites, who do not practice circumcision, be included in a blessing given specifically at the covenant of circumcision? [רמב״ן]. To resolve this, it is explained that becoming the father of many nations is a general reward given to Abraham for his obedience, even if not all his descendants keep the practice [מזרחי], while the unique, intimate covenant itself is reserved strictly for the Israelites [גור אריה].

A second, prominent approach suggests that the promise of nations refers exclusively to the Israelites, viewing them as a collection of distinct tribes or communities [רמב״ן, רד״ק, נתינה לגר]. They are described in the plural because the future nation would be composed of diverse groups, each with its own unique character and destiny—such as the military might of Judah, the commercial enterprise of Zebulun, and the deep scholarship of Issachar. Through this diversity, the Israelites are meant to serve as a model for all of humanity, demonstrating that serving God is not limited to one specific type of person or profession [רש״ר הירש]. On a broader spiritual level, this implies that Abraham's descendants would eventually spread throughout the world to teach, enlighten, and guide the minds of other nations [העמק דבר].

Finally, the promise culminates with the guarantee that kings will emerge from Abraham. Because a large group of people does not automatically possess political independence, God adds the explicit promise of sovereignty. Abraham's descendants will not be permanently subjugated to others; they will produce their own monarchs and rulers [מלבי״ם, שד״ל, ביאור שטיינזלץ]. These rulers will be powerful figures who will also hold influence over other nations, hinting at the past glory of the Israelite monarchy and looking forward to the future Messianic era [שד״ל, נתינה לגר]. Ultimately, this political power serves a higher purpose, as these great kings, like Solomon and the future Messiah, will use their influence to eradicate idolatry from the world [העמק דבר].
