Most of the plot takes place in an area known as the Fertile Crescent, which lies in the modern-day Middle East. There are three examples of this contradiction in Genesis. The sexual tradition of concubines, homosexuality, and sexual violence and dominance, or rape, of women.
The sexual tradition of concubines in the early biblical era contradicts the teachings of marriage and love by God. The first time we read about concubines is in the Abraham story. Sarah is barren so she gives Abraham her own servant to act as a concubine in hopes of producing an heir. The concubine produces a child named Ishmael. At the very beginning of Genesis, God himself said that sex should be saved for man and woman who are married. Abraham and many other Patriarchs remarkably deny God. The need for an heir is greater and more important to them than following God's teaching and limiting sex to one's marriage.
Early accounts of homosexuality in the Fertile Crescent always contradict Gods teaching of sex and marriage between man and woman. We read about homosexuality in the story of Sodom and Gomorrah. God is planning to destroy the cities of Sodom and Gomorrah because their citizens practiced homosexuality, along with other deviant sexual acts. Most of the people of Sodom and Gomorrah were not believers in God and his teachings, although word of this deity's teachings and morals must have passed through the city. There was bound to be at least one person in the cities that heard about God and his teaching about homosexuality. Scholars believe that the citizens of Sodom and Gomorrah were so twisted and confused at that point, that the homosexuality became second nature to them. Despite it all, the actions of these two cities contradict any teaching or moral lesson from God or anybody else for that matter.
Accounts of rape and molestation in the Book of Genesis definitely contradict what God is teaching about respect and equality towards women. We read about rape and sexual violence in the story of Dinah, the daughter of Jacob. Shechem, a foreign prince, wanted Dinah as his wife. He abducted her and lay with her. Shechem, a foreigner, probably did not hear of God's moral teachings on this kind of behavior. Although, when the prince abducted her and lay with her, there were many people, who already heard and understood God's teaching that could have stopped him. Besides the fact that Shechem did not hear of this god's teaching, rape was probably against his own conscious moral values.
