Proverbs 13:12-15 (KJV)
12 Hope deferred maketh the heart sick: but when the desire cometh, it is a tree of life.
13 Whoso despiseth the word shall be destroyed: but he that feareth the commandment shall be rewarded.
14 The law of the wise is a fountain of life, to depart from the snares of death.
15 Good understanding giveth favour: but the way of transgressors is hard.
