The answer is: He was younger

Job 32:4

Elihu, a character who enters the scene later in the Book of Job, is a fascinating figure! His choice to wait silently while Job's three friends conversed reveals cultural respect—a hallmark of ancient societies that valued age and wisdom. By holding back initially, Elihu communicates his humility and acknowledges strict social decorum. Despite being younger, he clearly has a lot to say, and he fills a crucial role in diversifying the perspectives debated in this profound dialogue about suffering and God’s justice.

What's interesting is Elihu's name, which means "My God is He." It provides a clever hint to his character's aim: He intends to bring divine insight into conversations steeped in human sorrow and conflict. Interestingly, his speeches lay the groundwork for God to appear later. Just as a skilled conductor raises anticipation before an orchestra's climactic moment, Elihu’s interjection builds suspense toward God’s voice, prompting the reader to reflect on a deeper understanding of the themes at play: suffering, righteousness, and divine purposes.

Moreover, while the views of Job's other friends revolve around traditional wisdom and a black-and-white view of divine retribution, Elihu leans into a fresh perspective, suggesting that suffering can be corrective rather than punitive. In hearing this young voice amid seasoned debate, readers are reminded that insights can come from unexpected places. Who knows what wisdom might emerge when one dares to speak up, even from a younger or unexpected voice in today’s conversations on faith and challenge?
