Purity Among the Priests

The prohibition against priests marrying a prostitute, a defiled woman, or a woman who had been divorced involved spiritual issues, not just moral matters. The priest was “holy to his God,” set apart as a representative between God and the people. The Lord wanted nothing to interfere with that representation. Moreover, in many of the cultures surrounding Israel, prostitution was often tied to religious rites.
