The answer is: Thigh

Genesis 32:25 - Jacob's encounter with the angel at Peniel signifies a pivotal moment in his spiritual journey, where he wrestles not only for physical blessings but also for reconciliation. Interestingly, this event foreshadows Israel's later struggles and God's enduring presence, reflecting themes of transformation and divine perseverance throughout Scripture.

Jacob’s fierce all-night brawl with the angel at Peniel is one of those riveting moments that captures the drama of human faith fighting against celestial purposes. When he has his thigh touched, setting him at a limp for the rest of his life, it serves as a metaphorical reminder that spiritual journeys can come with challenges and transformations. That limp isn’t just about physical toughness; it shows how encounters with the divine leave us bent but blessed.

This pivotal scene keyword “wrestle” can actually echo throughout Scripture — from Jacob’s grand tales to passionate declarations in the Psalms. It’s fascinating to see how this one act not only marks Jacob, turning him into Israel—the "one who struggles with God"—but also prefigures Israel’s national character through centuries, enduring struggles yet always seeking divine favor.

Interesting tidbit: the “thigh turned out of joint” is where the dietary prohibition within the Mosaic law comes from—the Jewish law forbids eating the sinew of the thigh from animals (Genesis 32:32). This physical mark seemed to influence many aspects of Israelite life, reminding them of the need for humility and reliance on God.

Throughout biblical narratives, moments like Jacob’s struggle illuminate God’s commitment to engage intimately with humanity, turning trials into transformations. It is assurance that the divine presence and purpose stands by, tending to our wounds, and often making us “stronger” through the weak moments of our lives.
