Fervent lips with an evil heart

Proverbs 26:1-28
Answer a fool according to his folly, or he will be wise in his own eyes.
A sluggard is wiser in his own eyes than seven people who answer discreetly.
Without wood a fire goes out; without a gossip a quarrel dies down.
As charcoal to embers and as wood to fire, so is a quarrelsome person for kindling strife.
Like a coating of silver dross((銀渣的塗層) on earthenware(陶器) are fervent lips with an evil heart.
24 Enemies disguise themselves with their lips, but in their hearts they harbor deceit. Though their speech is charming, do not believe them,  for seven abominations fill their hearts. Their malice may be concealed by deception, but their wickedness will be exposed in the assembly.
What is more likely than that he should then have turned his attention to the classic wisdom of Solomon? At any rate, it was his people who published this collection of Solomon's proverbs.
Why?
Do not answer fool with right answer but according to his folly.
There is no way to a sluggard who does not work for himself.
Do not gossip, quarrel dies down.
Be care of the enemies and evil man their lips is charming, do not believe them. No matter what they have done, their wickedness will be exposed in the assembly. For God is the sovereign Lord.
How?
Be wise to talk and be wise to listen and watch each one. Do not trust everything people says.
