Proverbs 26:22-24

Amplified Bible

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].^(A)
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.
²⁴ 
He who hates, disguises it with his lips,
But he stores up deceit in his heart.
