The answer is: He was younger

Job 32:4

In the fascinating drama of the Book of Job, Elihu, the young figure in the narrative, chooses to listen attentively before voicing his thoughts. This may seem like mere courtesy at first glance, but it reveals a deeper cultural backdrop. In ancient Israelite society, respect for age was paramount, and younger people were expected to gain wisdom by observing and learning from their elders. Elihu’s patience not only highlights his deference but also sets the stage for his fresh perspective.

Interestingly, Elihu’s insights contain a shift in tone compared to the earlier dialogues. Where Job’s friends heavily leaned on a simplistic understanding of divine justice—arguing that Job must have sinned because he was suffering—Elihu introduces a more nuanced idea that aligns suffering with personal growth and spiritual communication with the divine. He implies that pain can sometimes lead to Enlightenment or call for introspection, an idea echoed in many philosophical thoughts throughout history.

Now, here’s a fun fact: Elihu's speech is quite lengthy; perhaps, it reflects his eagerness to articulate a different understanding. The Book of Job is also considered one of the oldest pieces of literature, sparking curiosity into how timeless themes of suffering, wisdom, and trust in a higher power have resonated throughout generations. So, when Elihu finally speaks, it’s as if we're being introduced to a new voice in the ancient quest for meaning that remains as relevant today as it was then.
