The answer is: Sand of the seas

Job 6:3 - Compare this to Pro 27:3 A stone is heavy, and sand is weighty, but a fool's provocation is heavier than both.

In Job 6:3, you can almost feel the weight of Job's despair as he compares his grief to the vast sand of the seas—a metaphor that encapsulates the enormity of anguish. Job, a man of great integrity, faces unimaginable suffering and it leads him to articulate the indescribable depth of his pain. Interestingly, when Job uses this imagery, it’s not just a poetic flourish; it reflects a universal truth about sorrow. Hasn’t everyone felt like waves of sadness are crashing over them, thick and unyielding like sand that makes each step in life feel heavier?

Christian wisdom literature, like Proverbs, presents us with a related insight in Proverbs 27:3, which suggests that while rocks and sand have weight, emotional turmoil can eclipse all of that. The wise saying reminds us of the heavy toll that conflict and provocation can take on the human spirit. This concept resonates universally—the burdens we common people carry can be vast yet invisible.

Here’s a fun fact: did you know the ancient Hebrews considered the number of grains of sand a sign of immeasurable issues or blessings? Just as Job can't count his sorrows, it's also salient how life's blessings, like grains of sand, often elude precise measurement. In both grief and grace, our experiences connect us, and Job’s struggle reminds readers throughout generations that pain is a universally shared experience.
