.... In some places, the authors intended to record factual statements, but in others, the authors did not have that intent at all. There are numerous books/passages in scrupture that were not written with the intent of being fact. Revelation, for example, was not intended to be taken as fact, let alone to be taken literally (unless you believe there will be a literal beast with seven literal heads and ten literal horns). Jesus' parables were not intended to be taken as factual. Song of Solomon is not intended to be a factual account.
Even in books that are intended accounts facts do not necessarily line up (which is not a problem for the believer, because they're not meant to). For example, when Jesus was crucified, Matthew says he was given vinegar, while Mark says he was given wine with myrrh. According to Matthew, Jesus' last words were "My God, my God, why hast thou forsaken me?", Luke says his last words were "Father, unto thy hands I commend my spirit", and John says his last word were "It is finished". When he was mocked and given a robe, Matthew says the robe was scarlet, while John says it was purple. At Jesus' tomb after the resurrection, Matthew records one angel, Mark records a young man, Luke records two men, and John records two angels.
Now, are these minor divergences important to the believer? No, because they're not important to the context of each account, and don't detract from scripture's inerrancy at all.
