but he harbors animosity in his heart.

His words seem softer than oil,

but they are really like sharp swords.

whose tongues are a sharp sword.

Psalms 64:3-5

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.

64:5 They encourage one another to carry out their evil deed.

They plan how to hide snares,

and boast, “Who will see them?”

109:2 For they say cruel and deceptive things to me;

they lie to me.

they attack me for no reason.

12:18 Speaking recklessly is like the thrusts of a sword,

but the words of the wise bring healing.
