The answer is: 40

Isaiah 40:31 - This verse emphasizes the renewing power of faith and patience. The imagery of soaring eagles symbolizes divine strength and resilience. Interestingly, this theme echoes in Psalm 103:5, which also highlights the rejuvenation of life through God’s grace, reinforcing the importance of hope and trust in difficult times.

Isaiah 40:31 paints a beautiful picture of spiritual empowerment, where those who wait on the divine can expect a kind of renewal that’s almost miraculous. The imagery of mounting up with wings like eagles is particularly striking. Eagles are known not just for flight, but for soaring to great heights with grace—a fitting analogy for the ascendant spirit that faith can inspire.

In the broader context of Isaiah 40, this message emerges just after a proclamation of comfort following a long period of hardship for Israel. It is about lifting one's gaze above immediate troubles, suggesting that reliance upon something greater can rekindle one's inner strength. Notably, the characteristic endurance signified here evokes the perseverance admired in Biblical heroes, echoing the determination seen in figures like Job and the mighty David.

This theme is further reflected in other Biblical passages, notably in Jeremiah 29:11, where God declares that He holds plans for hope and a promising future. It suggests that waiting is not idling but a form of active trust and preparation.

Fun fact: Eagles can fly as high as 10,000 feet and are a symbol in various cultures, often representing vision and freedom. Such pillars of strength unite the narrative of sacred texts with the reflective understanding of human experience, illustrating how hope can renew our spirits just as much today as it did in ancient times.
