Proverbs 15:13-15

Amplified Bible

¹³ 
A heart full of joy and goodness makes a cheerful face,
But when a heart is full of sadness the spirit is crushed.^(A)
14 
The mind of the intelligent and discerning seeks knowledge and eagerly inquires after it,
But the mouth of the [stubborn] fool feeds on foolishness.^(B)
15 
All the days of the afflicted are bad,
But a glad heart has a continual feast [regardless of the circumstances].
