[6.] But I have no [skill of] speech, you say. But there is no need of [skill of] speech nor of eloquence. If thou see a friend going into fornication, say to him, Thou art going after an evil thing; art thou not ashamed? Dost thou not blush? This is wrong. ‘Why, does he not know’ (you say) ‘that it is wrong?’ Yes, but he is dragged on by lust. They that are sick also know that it is bad to drink cold water, nevertheless they need persons who shall hinder [them from it]. For he who is suffering, will not easily be able to help himself in his sickness. There is need therefore of thee who art in health, for his cure. And if he be not persuaded by thy words, watch for him as he goes away and hold him fast; peradventure he will be ashamed.
