It seems as if a variable of 6-9 would improve even on that. Throw in 9 characters worth of garbage SOMETIMES. That is, an un-solveable captcha.
The only serious problem I had with all of that is that Job's original family and servants remained dead. I suppose you COULD make the argument that they are with God in heaven or will be on earth in paradise eventually. You could … but you wouldn't find any actual scripture to support that contention.
No … the trails of Job are just a lesson to keep the obedient in line. God would not be unjust to the servants and the children … but this story teller totally discarded them.
