It's very difficult to find passages in the Bible without passages which contradict them under (sometimes) different circumstances.


You said it. Not only do we have a difference between "our culture" and "their culture", but "their culture" is really many. Classic example is the shift of emphasis for acceptable marriage partners: from an endogamous strategy (ie -- marrying your niece is best) to an aggressive, exogamous strategy (ie -- take the women of other clans and deny them ours), where women become a political and economic commodity. Then after the exile, a more defensive posture and a focus on producing offspring. Not understanding this shift has produced some odd commentary over the millenia.
