Proverbs 26:21-23

Amplified Bible

²¹ 
Like charcoal to hot embers and wood to fire,
So is a contentious man to kindle strife.^(A)
22 
The words of a whisperer (gossip) are like dainty morsels [to be greedily eaten];
They go down into the innermost chambers of the body [to be remembered and mused upon].^(B)
23 
Like a [common] clay vessel covered with the silver dross [making it appear silver when it has no real value]
Are burning lips [murmuring manipulative words] and a wicked heart.
