Analysis of information sources in references of the Wikipedia article "Job (biblical figure)" in English language version.
Determining the time and place of the book's composition is bound up with the nature of the book's language. The Hebrew prose of the frame tale, notwithstanding many classic features, shows that it was composed in the post-Babylonian era (after 540 BCE). The poetic core of the book is written in a highly literate and literary Hebrew, the eccentricities and occasional clumsiness of which suggest that Hebrew was a learned and not native language of the poet. The numerous words and grammatical shadings of Aramaic spread throughout the mainly Hebrew text of Job make a setting in the Persian era (approximately 540–330) fairly certain, for it was only in that period that Aramaic became a major language throughout the Levant. The poet depends on an audience that will pick up on subtle signs of Aramaic.
