Ecclesiastes 7:4-6

Amplified Bible

⁴ 
The heart of the wise [learns when it] is in the house of mourning,
But the heart of fools is [senseless] in the house of pleasure.
⁵ 
It is better to listen to the rebuke of the wise man and pursue wisdom
Than for one to listen to the song of fools and pursue stupidity.
⁶ 
For like the crackling of [burning] thorn bushes under a pot,
So is the laughter of the fool;
And this too is vanity (futility).
