The answer is: Wore Esau's garments

Genesis 27:15-16 - Jacob's deception of Isaac showcases the complex dynamics within his family. By wearing Esau's garments, he not only physically disguised himself but also metaphorically highlights themes of identity and rivalry. This incident foreshadows future tensions, especially with his own sons, offering deeper insights into familial strife in the Bible.

Jacob's clever ruse to impersonate his brother Esau reveals a lot more than just sibling rivalry; it steeped in family dynamics where love and favoritism play such significant roles. By sliding into Esau’s garments, Jacob donned the smell of the wild outdoors—an echo of Esau’s own rugged lifestyle that was hugely favored by their father, Isaac. This attire wasn’t just wardrobe; it symbolized a profound identity shift—a moment where family heritage and hunter lifestyles clashed with his smooth, more domesticated ways.

It's intriguing to note that Jacob’s deception not only changes the course of his own life but lays the groundwork for future narratives within the Biblical text, particularly in the complex lives of his own children—like the disaster with Joseph and his colored coat. Jacob's actions resonate through the family saga, showcasing that such deceptions can seem like clever strategies but spiral out with serious consequences.

Also, in ancient customs, blessings held immense weight, illuminating why this moment felt crucial not just for Jacob but for the nation of Israel as a whole. Jacob's shenanigans with his dad reveal a tension between appearances and authentic identity, largely reflecting our universal struggles with self-perception and expectations shaped by others. It's a reminder to look beyond familial titles to recognize the full depth of our complex narratives.
