The renaming of Jacob stands as a profound turning point that redefines not only a single man's identity but the very character of the nation that will emerge from him. While the angel he wrestled with in the night had previously promised a new name, that encounter was merely a glimpse into the future. Now, God Himself appears to confirm and establish this transformation, making the new title a reality [רמב״ן, הטור הארוך, שטיינזלץ].
This event introduces a striking contrast between two distinct identities. The original name, Jacob, is rooted in concepts of ambush and cleverness. It recalls the hidden, indirect ways he secured the blessings from his brother Esau. In contrast, the name Israel represents authority, leadership, and openness. It declares that the blessings truly belong to him by right and were achieved through honest, open victory [רש״י, שד״ל, מזרחי, דברי דוד]. Retaining the original name serves as a reminder that even his past actions, which may have appeared deceptive, were ultimately just and directed by God [אלשיך].
A fascinating difference emerges when comparing this moment to the renaming of Abraham. While Abraham's original name was entirely erased and forbidden from use, Jacob's original name remains intact. The primary approach among commentators is that the name Jacob is never canceled. Instead of replacing it, the new title is added, meaning he will no longer be known by his first name alone, but will carry both identities simultaneously [אבן עזרא, חזקוני, רבנו בחיי]. The phrasing used by God actively joins the new name to the old one, linking them together [הכתב והקבלה]. Yet, a clear hierarchy is established. Israel becomes the primary identity, expressing greatness and high stature, while Jacob takes on a secondary role [כלי יקר, תורה תמימה, הכתב והקבלה].
This dual identity is not accidental. It mirrors two parallel tracks in God's relationship with the world and the historical journey of the Israelites. The name Jacob symbolizes life governed by the laws of nature. It reflects the struggle within the material world and periods of exile, where the nation must survive through indirect means and moments of vulnerability. Conversely, the name Israel represents miraculous, spiritual existence. It captures the power to strive with both God and humanity, pointing toward an ultimate redemption where the nation walks openly and proudly [מלבי״ם, העמק דבר, כלי יקר].
Because a name reflects the very essence of a soul, Jacob's inner being naturally contains both of these realities. Both the man and his future nation require these two names to fully express the diverse challenges, triumphs, and eras they will experience throughout history [אור החיים, כלי יקר].
