The answer is: Benjamin

Genesis 35:16-18 - Benjamin was the youngest son born to Rachel, Jacob's favoured wife, while Leah bore six of Jacob's other children. Interestingly, Rachel died during childbirth, and Benjamin's name means "son of my right hand," reflecting his special status in the family. This highlights the complex dynamics between Jacob’s wives and their struggles for his affection.

The family dynamics of Jacob, Leah, and Rachel serve as a rich tapestry of storytelling and deeper human emotions in Genesis. Each child born reflects not just physical presence but the nuanced relationships within this family. Leah, desperate for Jacob's love, bore him six sons and a daughter, a testament to her longing for acknowledgment in a competition for favor. Her first four sons—Reuben, Simeon, Levi, and Judah—each symbolize a glimmer of hope for her affection from Jacob.

On the other hand, Rachel's battle with barrenness created tension between the sisters. Though she eventually gave birth to Joseph and then Benjamin, her elation was shadowed by the bitter irony of her passing during Benjamin's reluctant arrival. To further explore the significance of Benjamin's name—it not only means "son of my right hand" but also signifies special privilege, much like how Benjamin's legacy continues through the tribe that would later emerge from him. This tribe would later take a significant role in Israeli history, producing notable figures including King Saul.

In biblical numerology, the name Benjamin holds significant value and connects to the themes of transformation and wrestling with identity. This entire narrative echoes the notion of striving for love, acceptance, and familial responsibilities—elements that resonate throughout human history. In such tangled relationships, the timeless quest for personal validation shines brightly.
