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.

The story of Jacob and Isaac is a captivating narrative replete with lessons about identity, allegiance, and the consequences of deception. When Jacob dons Esau’s clothes, he steps into a clever ploy that starkly contrasts the brothers’ roles; Esau, the rugged hunter, vs. Jacob, the smooth-skinned homebody. This isn’t just about physical appearance—clothing in biblical times often symbolized social roles and identity. By donning Esau's garments, Jacob transcends simpler definitions of identity. He becomes a mirror of their father's expectations and societal norms, highlighting the tensions that often arise in family dynamics.

Interestingly, this biblical ruse resonates across different cultures and findings, as many folklore tales include similar themes of disguise and mistaken identity. Throughout the biblical text, deception often has profound implications. Remember when David took on different personas to avoid King Saul? Or think of Esther, who concealed her identity to save her people. Each experience hence echoes the notion that who we present ourselves to be can dramatically influence our circumstances, as exhibited by the idiosyncratic roles we sometimes play in our families.

Moreover, looking closely, this event sets a precedent for later familial conflicts among Jacob's own sons and their fierce rivalry with Joseph, which reflects the age-old rivalry theme once again. The shadow of this deception looms large, painting a vivid picture of how resolution can often shift into turbulence, making these relationships as intricate as a woven garment.
