This is a comprehensive study of sexuality in the Old Testament, discussing social, legal, ethical, and theological factors. There is an extensive discussion of the interrelationships between various parts of the Old Testament. Davidson starts with Eden as a model for human sexuality, gives a close analysis of the laws in the Torah in light of that experience, and then moves exhaustively into a topic-by-topic discussion of how things functioned in ancient Israel, mining all parts of the Old Testament for whatever light can be shed on the topic, and finally concluding with the Song of Solomon as a model for fulfilled sexual experience.
While the primary focus is on the Old Testament, Davidson occasionally addresses the New Testament outlook and discusses application to contemporary ethical questions. Discussions with other theologians are usually carried on in the footnotes, but no less enlightening for all that. This is not a complete Christian theology of sexuality, but it is a necessary building block for any such effort.
The book would probably have benefited from a better editing job, as it is frequently somewhat repetitive. This does make it more useful as a reference source, however, as you don't have to read the whole thing to pick up every nuance of the topic you're investigating.
Highly recommended for those interested in the history of sexuality, the theology of sexuality, contemporary pastoral issues, gender history, and the social history of ancient Judaism
