Reading the Old Testament Ethically

It can sometimes be difficult for the modern reader to know whether the author of an Old Testament book is commending or condemning certain acts. Professor Wenham turns to modern literary theory and ethical analysis to show how two quite different books of the Old Testament, Genesis and Judges, offer ethical models of behaviour. He focuses on the attitudes of the authors rather than the morals of the characters in the stories, and argues that these models are actually closer to New Testament ideals than has previously been recogised.
