Concerning the time the events recorded took place there have been many views ranging from the patriarchal age of Abraham, Isaac and Jacob (beginning about 2100 B.C.) to the sixth century B.C.
Internal evidence suggests that Job lived in the patriarchal period. The length of his life (either 140 or about 210 years; 42:16) is similar to that of Terah (205 years), Abraham (175 years), Isaac (180 years), and Jacob (147 years). The writer measured Job's wealth in terms of his livestock. This is how Moses evaluated the wealth of Abraham and Jacob (1:3; 42:12; cf. Gen. 12:16; 13:2; 30:43; 32:5). The Sabeans and Chaldeans (1:15, 17) were nomads during the patriarchal period but not later. Job was the priest of his family (1:5) a condition that became less common when nations in the Near East developed more organization. Names of people and places in the book were also common in the patriarchal age (e.g., Sheba, Tima, Eliphaz, Uz, Job). Genesis, the Mari documents, and the Egyptian Execration texts, all of which refer to life in the Near East at this time, also refer to these names.
"The idea that Job has an Edomite background is as old as the LXX, which equates Job with Jobab, king of Edom (Gn. 36:33)."1
"Most recent [liberal] writers are agreed that in its original form the book was of post-exilic origin, and the secondary parts of later composition."2
Internal evidence, however, has led many careful students of the book to conclude that it was the work of one person. Perhaps someone else added a few minor touches later under divine inspiration (e.g., 42:16-17). If Job lived in the patriarchal period, as the evidence seems to suggest, what clues are there that someone did not write it then or very soon afterwards? The detailed recounting of the conversations that took place certainly suggests a composition date fairly close to that of the actual events. That has been the position of Jewish and Christian scholars until destructive criticism became popular in the last few centuries. Critics point to the fact that oral tradition was very exact in the ancient world and that people could have transmitted Job's story by mouth for generations and retained its purity. With the Holy Spirit's superintending work it could have been, but there is no evidence that this is what happened. Literacy was widespread in the ancient world at this time.3Critics further point out that in the process of social evolution composition of a work such as this book was more typical at a date much later than the patriarchal period. Yet again there is no evidence that someone wrote it later. The simpler explanation is that someone wrote it early. Since there is no proof that someone wrote it later, most conservative scholars have continued to prefer the traditional early date of composition theory.
