Proverbs 29:20-22

Amplified Bible

²⁰ 
Do you see a [conceited] man who speaks quickly [offering his opinions or answering without thinking]?
There is more hope for a [thickheaded] ^[a]fool than for him.
²¹ 
He who pampers his slave from childhood
Will find him to be a son in the end.
²² 
An angry man stirs up strife,
And a hot-tempered and undisciplined man commits many transgressions.
