16He that withholdeth her, (is) as if he holdeth (the) wind; and voideth the oil (out) of his right hand. (He who trieth to hold her, is like him who trieth to hold the wind; and like him who trieth to pick up oil with his fingers.)
17Iron is whetted by iron; and a man whetteth the face of his friend. (Iron is sharpened by iron; and a man sharpeneth his friend’s mind.)
