Proverbs 26:21-22

Like charcoal to hot embers and wood to fire, So is a contentious man to kindle strife. [Prov 15:18; 29:22] 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]. [Prov 18:8]
