The answer is: He was red and hairy

Genesis 25:25 - Esau's distinctive appearance at birth, described as "red and hairy," mirrors his later life as a skilled hunter and man of the wilderness. This contrast with Jacob, who is portrayed as sheepish and reflective, foreshadows their divergent paths. Interestingly, red is often associated with both passion and danger, themes that profoundly influence their story.

Esau’s fiery hair and ruddy complexion are striking details right from his entrance into the world. It's fascinating how these characteristics not only define him at birth but are also echoed in the robust life he leads further along his journey. A skilled hunter, Esau exemplifies traits archetypal of rugged masculinity; his physicality becomes a lasting image paired with his rough lifestyle—evidence of man’s raw, untamed essence.

The color red throughout the Bible often carries significant symbolism. It’s connected not just to the physical but also evokes deeper themes, such as sacrifice and vitality. For instance, red is prevalent in biblical narratives around sin and redemption, including blood symbolism, which speaks volumes about life, death, and atonement—topics ultimately woven into the tapestry of Esau's later decisions.

Furthermore, there’s speculative humor in how many regard Esau's appetite for 'red stews,’ which he famously trades against his birthright. This image not only captures his human fraility but also incites reflections about choices and consequence.

Contrastingly, Jacob—quiet, more reflective— embodies the archetype of the thoughtful, the planner. Their juxtaposing lifestyles add layers to their sibling dynamic, rich in story nuances since birth. Jacob’s stitching this narrative of striving for the blessings reflects broader human themes of aspiration and the relentless search for identity and acceptance. Overall, Esau and Jacob's divergence speaks to the larger theme of individuality clashing with familial legacy, making their story captivating across millennia.
