One should not place trust in past purity, for even David, the most righteous, and Solomon, the wisest, found their hearts darkened through their associations with women. To prevent anyone from thinking that their virtue is secure in the company of a female relative, it is important to recall how Tamar was wronged by Amnon, who feigned illness. Thus, both monks and nuns are called to lead lives of such profound chastity that they can witness honorably not only before God but also in the eyes of humanity, providing a worthy example of sanctity for those who follow them.
