He that teacheth a fool, is like one that glueth a potsherd together. 8He that telleth a word to him that heareth not, is like one that waketh a man out of a deep sleep. 9He speaketh with one that is asleep, who uttereth wisdom to a fool: and in the end of the discourse he saith: Who is this? 10Weep for the dead, for his light hath failed: and weep for the fool, for his understanding faileth. 11Weep but a little for the dead, for he is at rest. 12For the wicked life of a wicked fool is worse than death. 13The mourning for the dead is seven days: but for a fool and an ungodly man all the days of their life. 14Talk not much with a fool and go not with him that hath no sense. 15Keep thyself from him, that thou mayst not have trouble, and thou shalt not be defiled with his sin.
