Iyyob

'Iyyob was a wealthy nomad in the Levant. Though his story is included in the Writings, the setting of his story is one of the oldest chronologically, esp. for a story as long and detailed as his.

There is an Egyptian text from the 1600s BCE that mentions and Ayyob, King of the Shutu, which very well may be the wealthy nomad warlord leading the proto-Hebrews.
