Proverbs 15:10-15 (KJV)
10 Correction is grievous unto him that forsaketh the way: and he that hateth reproof shall die.
11 Hell and destruction are before the LORD: how much more then the hearts of the children of men?
12 A scorner loveth not one that reproveth him: neither will he go unto the wise.
13 A merry heart maketh a cheerful countenance: but by sorrow of the heart the spirit is broken.
14 The heart of him that hath understanding seeketh knowledge: but the mouth of fools feedeth on foolishness.
15 All the days of the afflicted are evil: but he that is of a merry heart hath a continual feast.
