Interpretation bridges the gap between critical and expository commentaries and combines the most exciting biblical scholarship with illuminating textual expositions.

persecuted, an Arabian patriarch who resided in the land of Uz (q.v.). While living in the midst of great prosperity, he was suddenly overwhelmed by a series of sore trials that fell upon him. Amid all his sufferings he maintained his integrity. Once more God visited him with the rich tokens of his goodness and even greater prosperity than he had enjoyed before. He survived the period of trial for one hundred and forty years, and died in a good old age, an example to succeeding generations of integrity (Ezek. 14:14, 20) and of submissive patience under the sorest calamities (James 5:11). His history, so far as it is known, is recorded in his book.
