    but the heart of fools proclaims their stupidity.

    but those who open their lips are ruined.

    those who shut their lips are smart.

¹³ Those who answer before they listen
    are foolish and disgraceful.

²³ Those who guard their mouths and their tongues
    guard themselves from trouble.
