In the book of Job we see God allowing Satan to test Job's character by stripping him of his health, his children, his servants, and his livestock, yet Job refuses to curse God. But how rich was Job and how much did he have to lose?
Aside from his ten children and numerous servants, Job 1:3 says he had "seven thousand sheep, three thousand camels, five hundred yoke of oxen, five hundred female donkeys."
Mogama of SearchWarp calculated the value of that livestock in 2009 dollars, coming up with a total of almost $5.3 million in animals alone, not counting his property and other possible assets. With wealth like that in that time, Mogama claims Job would have been up there with today's "Bill Gates, William Buffet, and Oprah Winfrey all rolled up in one."
It's not a wonder that verse 3 describes Job "as the greatest of all the people of the East." He truly had the most to lose when it came to material wealth. But despite being rendered destitute in a single day on top of losing the children he deeply loved, Job still blessed the Lord who he believed was the true provider of all that he had.
In the end, after Satan's attacks had ceased, the God who had allowed so much to be taken away from Job gave back two-fold and blessed him with more children, a rich and full life, and a greater understanding of his Heavenly Father.
