When it pertains to property, we likewise get away with a lot. Women in the Bible are chattel, barely worth more than a sheep but definitely less than a cow. Whatever happens to them is just part of the story and not really important.
The Jews have a really good way of explaining the lessons without focusing on whether it is factual. If you're looking at the moral of the story, I'd recommend looking at Orthodox Jewish scholars for answers, the rest is just ancient story.
The interesting part is that Jesus came from a lineage of whoremongers and illegitimate children with a distant and somewhat dubious claim to the throne of David. It's why the Jews will never accept Jesus and why the New Testament is basically contradictory descriptions of lineage and apologetics on the character of Jesus.
