The Tongue and Mouth of Fools vs. the Wise
The one who guards his mouth preserves his life ;
The one who opens wide his lips comes to ruin (Pro. 13:3)
The heart of fools is in their mouth: but the mouth of the wise is in their heart (Ben Sira 21:26)


"A fool finds no pleasure in understanding but delights in airing his own opinions" (Pro. 18:2).

"Do not think of yourself more highly than you ought" (Rom 12:3)

“Professing themselves to be wise, they became fools” (Rom 1:22).

“... these men blaspheme in matters they do not understand” (2 Pe. 2:12)

For a fool speaks nonsense , And his heart inclines toward wickedness : To practice ungodliness and to speak error against the LORD (Isa 32:6)

When words are many, sin is not absent, but he who holds his tongue is wise (Pro. 10:19)

"Do you see a man who speaks in haste? There is more hope for a fool than for him" (Pro. 29:20).

"If you have played the fool and exalted yourself ... clap your hand over your mouth!
(Pro. 30:32).

Even a fool is thought wise if he keeps silent, and discerning if he holds his tongue
(Pro. 17:28)

A fool's mouth is his undoing, and his lips are a snare to his soul (Pro. 18:7)

The Wise

"The discerning heart seeks knowledge, but the mouth of a fool feeds on folly" (Pro. 15:14).

“The tongue of the wise useth knowledge aright : but the mouth of fools poureth out foolishness” (Pro. 15:2).

"Reckless words pierce like a sword, but the tongue of the wise brings healing" (Pro. 12:18).

“The tongue of the wise useth knowledge aright : but the mouth of fools poureth out foolishness” (Pro. 15:2).

Words from a wise man's mouth are gracious, but a fool is consumed by his own lips (Ecc. 10:12)





“Whoever would love life and see good days must keep his tongue from evil and his lips from deceitful speech. He must turn from evil and do good; he must seek peace and pursue it. For the eyes of the Lord are on the righteous and his ears are attentive to their prayer, but the face of the Lord is against those who do evil.” (1 Pe. 3:10-12)

Now the fruit of righteousness is sown in peace by those who make peace" (Jas 3:2,6, 16-18).
