Date of The Book of Job

Date - 2180 BC Approximately. It is uncertain exactly when the book was written and who wrote it but Jewish tradition says Job was its author. It is interesting that the name of Yahweh appears over and over in the book of Job, and his name was unknown prior to the time of Moses (Exodus 6:2-3). The name of the Egypt is used in poetic form a couple times (Job 9:12-13, Job 26:12-13) and when it is used this way there is implications that the author of the book new about the exodus from Egypt.
