The answer is: He was younger

Job 32:4

Elihu, in the Book of Job, is a fascinating character! His decision to wait in silence tells us something significant about respect and the wisdom that can come with patience. Back in those times, age was associated with wisdom, which explains why Job's older friends had a lot to say. But Elihu, being younger and likely taking it all in, teaches us that sometimes, it’s vital to listen before we speak. His eagerness to share his thoughts later reflects a boldness in wanting to present a different perspective, highlighting that maturity doesn’t solely stem from age.

Interestingly, Elihu’s speeches introduce a fresh breeze of rational arguments into the narratives filled with lamenting and complaints. While older friends focus on traditional wisdom, Elihu eliminates some of the redundancies and dives abruptly into discussing God’s greatness. He emphasizes God as a communicator through various forms—nature, dreams, and even suffering—pointing to divine messages in the midst of hardship.

Another fascinating tidbit is that Elihu isn’t rebuked for his words, unlike Job's other friends. This could hint at Elihu’s role as a bridge to spiritual insight, leading Job towards a more profound revelation of God's nature. As readers, it reminds us that sometimes, some of the most enlightening perspectives can come from unexpected sources. After all, wisdom can sprout from anywhere, much like a wildflower in a field!
