Book of Proverbs 26-28 As a dog returneth to his vomit

Proverbs 26-28

There is a lot of good writing in this book.  I especially like;

26:11 As a dog returneth to his vomit, so a fool returneth to his folly.

Then there is; 

27:18 Whoso keepeth the fig tree shall eat the fruit thereof: so he that waiteth on his master shall be honoured. Jesus curses and kills a fig tree later in the book.  Is this foreshadowing? ;-) How could this be; 28:14 Happy is the man that feareth alway: but he that hardeneth his heart shall fall into mischief. I did learn something in proverb 29.  It's necessary to beat children and slaves in order to teach them. Good to know if I ever acquire either.
