Ecclesiastes 7:5-7

Common English Bible

⁵ It is better to obey the reprimand of the wise
    than to listen to the song of fools,
⁶     because the fool’s merriment
    is like nettles crackling under a kettle.
        That too is pointless.
⁷ Oppression turns the wise into fools;
    a bribe corrupts the heart.
