Wiki Details
Job (English: ; Hebrew: אִיּוֹב 'Īyyōv; Greek: Ἰώβ Iṓb) is the central figure of the Book of Job in the Bible. In Islam, Job (Arabic: أيوب, romanized: ʾAyyūb) is also considered a prophet.
The Book of Job presents him as a family man who is beset with disasters that take away his family and possessions; this scenario is intended to test his faith in God. Job struggles to understand while reflecting on his despair. Despite this, he consistently remains devout.
The language of the Book of Job, combining post-Babylonian Hebrew and Aramaic influences, indicates it was composed during the Persian period (540–330 BCE), with the poet using Hebrew in a learned, literary manner.
