New International Version
Then the LORD said to Satan, "Have you considered my servant Job? There is no one on earth like him; he is blameless and upright, a man who fears God and shuns evil. And he still maintains his integrity [H8538], though you incited me against him to ruin him without any reason."
Job was unique. There was no one like him.
H8538 applies specifically only to Job's character. Outside of the book of Job, it appears only once in Proverbs 11:3
The integrity of the upright guides them,
but the unfaithful are destroyed by their duplicity.
The word is related to being faithful.
