The book of Job was, perhaps, the first written among the Old Testament books. From the people mentioned in the book it would seem to have been told between the time of Abraham and the Exodus of the children of Israel from Egypt. Perhaps between 40 to 80 years before the exodus. This would place the time of writing between BC 1571 and BC 1531. Its author may have been Moses. The place of the events described is in the area of Midian, to the south-east of the Promised Land. There are many views as to whether the events told actually happened, or were rather an ancient drama to instruct faithful believers. From what has been written in James 5 it would seem more likely to be a record of what actually occurred (James 5verses11). What an introduction to the man Job - he was the greatest of all men from the east. But, chiefly, his greatness lay in that, he "was blameless and upright, one who feared God and turned away from evil" (verse 1 ESV). He is a family-oriented man, who brought up his family in "the fear and admonition of the LORD". Verses 6-12 introduces us to "the Satan" of the book. Note, that this time I have used an upper-case S, because the book is dealing with a specific adversary, or opponent - as the Hebrew word indicates - though the name of this adversary is not revealed). As a common noun the word occurs numerous times in the Old Testament, and in the vast majority of cases is without the definite article ("ha" in the Hebrew). The majority of the occurrences where the definite article is used are in Job and Zechariah (both of these books focus on an identifiable opponent, and in these two books that opponent is easily identified). Verse 6 speaks of a day when God's children presented themselves before Him and this tells of a time for gathering together for a specific purpose - such as when Israel gathered at the appointments of the Festivals. Or, when in this age, believers gather to memorialise the Lord's supper (coined "communion"). Job's adversary may have been a disaffected believer. He proposes that Job's reverence for God is conditional on Job's favoured status. God's advice to the adversary is that Job's uprightness is not related to the blessings Job receives. To prove the point God, for a time, gives the opponent power to test this. The Satan has no independent power (see Job 42verses11). From verses 13-21 we read of a succession of disasters which the adversary requested God to bring upon Job and his family.
The chapter finishes by telling us that Job failed not. Job admits that it is Yahweh's right to treat us as He sees fit. Again, when the believers assemble together the adversary is there. Job's opponent is again confronted by God; but the adversary says that all mankind are essentially selfish. Yes, but says Job's foe, smite his health and Job will forsake his uprightness. This affliction of Job's health was permitted, and Job was smitten with leprosy (a loathsome, itching, superinfection of boils). Job receives no let up from the pain that this induced. Job's wife could endure no more and calls for her husband to curse God and die. Job rebukes her folly. From verses 11-13 we are told that when the news of their friend's suffering reached Job's 3 friends they came and sat in silence with him for seven days.
