Psalms 64:3

Who whet their tongue like a sword, and bend their bows to shoot their arrows, even bitter words:

Who whet their tongue like a sword - (Psalms 57:4; Psalms 59:7.) Not mere common slanders; but those which aim at the destruction of the slandered person, as was the case in the slanders directed by Saul and his faction against the destruction of the slandered person, as was the case in the slanders directed by Saul and his faction against David.
