Ecclesiastes 7:5-7

Amplified Bible

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).
⁷ 
For oppression makes a wise man foolish,
And a bribe corrupts the [good judgment of the] heart.
