After initially granting blessings under the mistaken impression of his son's identity, Isaac now blesses Jacob with complete, clear awareness. This second blessing serves as an official confirmation of the previous ones. It makes it clear that Jacob's selection did not stem from deception, but rather from a total recognition that he is the chosen offspring destined to bring forth the nation [ביאור יש״ר, חזקוני].
Isaac opens his blessing by invoking a specific name of God. The primary approach among commentators is that this title refers to the God whose blessings and divinity are entirely sufficient to shower endless abundance upon all of creation [רש״י, שפתי חכמים, מזרחי, חזקוני, ביאור שטיינזלץ]. Another perspective suggests this name reflects the God who placed limits on His world, adapting and restricting the revelation of His glory to fit within the physical realm [העמק דבר]. Invoking this specific name at this moment is highly intentional. It acts as a prophecy that God will later reveal Himself to Jacob using this very title [העמק דבר]. Furthermore, it is an ideal name to call upon for protection during times of distress and danger, perfectly suited for Jacob as he embarks on his journey fleeing from Esau [יריעות שלמה].
Because Jacob is setting out on a long journey, he faces the natural hardships of travel, which typically diminish a person in three areas: their wealth, their ability to have children, and their personal status. To counter these exact vulnerabilities, Isaac grants a threefold blessing [אלשיך]. First, he blesses Jacob with financial success, physical protection, and the resources needed to build a home [ספורנו, רש ר הירש, אלשיך]. Next, he offers a blessing for abundant children [ספורנו, אלשיך, רש ר הירש]. A unique interpretation links this promise of fertility to the future justice system, ensuring that Jacob's descendants will be physically whole and fit to serve as judges, allowing them to eventually establish a proper high court [פרדס יוסף]. Finally, Isaac blesses him with an elevation in spiritual status, granting him the strength to pass his spirit down to future generations [ספורנו, רש ר הירש].
The ultimate goal of these blessings is for Jacob to grow into a massive nation [ביאור שטיינזלץ]. This future is described using a combination of concepts that represent both unity, like a single gathered assembly, and diversity, like a multitude of different peoples. Jacob will indeed have diverse descendants with distinct personalities, eventually dividing into separate tribes with their own unique customs. However, unlike the descendants of Abraham and Isaac, who splintered into hostile, separate nations like Ishmael and Esau, all of Jacob's offspring will remain deeply united, much like different branches growing from a single root. None of them will be rejected, and together they will form a complete, cohesive community [העמק דבר, נתינה לגר, רש ר הירש, אלשיך, צפנת פענח]. This tremendous blessing of offspring is also deeply tied to the future inheritance of the land. The people and the land depend entirely upon one another, serving together as the essential condition for God to rest His presence among them [מלבי״ם].
