Proverbs 15:13-15

¹³A merry heart maketh a cheerful countenance: But by sorrow of the heart the spirit is broken.

¹⁴The heart of him that hath understanding seeketh knowledge: But the mouth of fools feedeth on foolishness.

¹⁵All the days of the afflicted are evil: But he that is of a merry heart hath a continual feast.
