A good person’s mouth is a clear fountain of wisdom; a foul mouth is a stagnant swamp.
Righteous chews on wisdom like a dog on a bone, rolls virtue around on his tongue. His heart pumps God’s Word like blood through his veins; his feet are as sure as a cat’s.
The mouth of a good person is a deep, life-giving well, but the mouth of the wicked is a dark cave of abuse.
You’ll find wisdom on the lips of a person of insight, but the shortsighted needs a slap in the face.
A bad motive can’t achieve a good end; double-talk brings you double trouble.
