Proverbs 26:20-22

26:20 Where there is no wood, a fire goes out,

and where there is no gossip, contention ceases.

26:22 The words of a gossip are like delicious morsels;

they go down into a person’s innermost being.

it is as effective as a sharp razor, O deceiver.

Psalms 64:3-4

64:3 They sharpen their tongues like a sword;

they aim their arrow, a slanderous charge,

64:4 in order to shoot down the innocent in secluded places.

They shoot at him suddenly and are unafraid of retaliation.
