Proverbs 18:7

Keep your heart with all diligence, for out of it is the wellspring of life.

So, then, my beloved brothers, let every man be swift to hear, slow to speak, and slow to anger;

Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear.

Whoever guards his mouth and his tongue keeps his soul from troubles.

“Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock.

The trouble he causes shall return to his own head. His violence shall come down on the crown of his own head.

Wise men lay up knowledge, but the mouth of the foolish is near ruin.

An evil man is trapped by sinfulness of lips, but the righteous shall come out of trouble.

He who guards his mouth guards his soul. One who opens wide his lips comes to ruin.

Death and life are in the power of the tongue; those who love it will eat its fruit.

It is better that you should not vow, than that you should vow and not pay.

The good man out of the good treasure of his heart brings out that which is good, and the evil man out of the evil treasure of his heart brings out that which is evil, for out of the abundance of the heart, his mouth speaks.

For we all stumble in many things. Anyone who doesn’t stumble in word is a perfect person, able to bridle the whole body also.

in whose eyes a vile man is despised, but who honors those who fear Yahweh; he who keeps an oath even when it hurts, and doesn’t change;

For by your words you will be justified, and by your words you will be condemned.”

the Lord knows how to deliver the godly out of temptation and to keep the unrighteous under punishment for the day of judgment,

When a man vows a vow to Yahweh, or swears an oath to bind his soul with a bond, he shall not break his word. He shall do according to all that proceeds out of his mouth.

David lamented with this lamentation over Saul and over Jonathan his son

David said to Joab, and to all the people who were with him, “Tear your clothes, and clothe yourselves with sackcloth, and mourn in front of Abner.” King David followed the bier.

Yahweh has made himself known. He has executed judgment. The wicked is snared by the work of his own hands.

In arrogance, the wicked hunt down the weak. They are caught in the schemes that they devise.

His mouth is full of cursing, deceit, and oppression. Under his tongue is mischief and iniquity.

You have proved my heart. You have visited me in the night. You have tried me, and found nothing. I have resolved that my mouth shall not disobey.

All those who see me mock me. They insult me with their lips. They shake their heads, saying,

Because of all my adversaries I have become utterly contemptible to my neighbors, a horror to my acquaintances. Those who saw me on the street fled from me.

I said, “I will watch my ways, so that I don’t sin with my tongue. I will keep my mouth with a bridle while the wicked is before me.”

For the sin of their mouth, and the words of their lips, let them be caught in their pride, for the curses and lies which they utter.

Their own tongues shall ruin them. All who see them will shake their heads.

As for the head of those who surround me, let the mischief of their own lips cover them.

Let the wicked fall together into their own nets while I pass by.

Instruct a wise person, and he will be still wiser. Teach a righteous person, and he will increase in learning.

One winking with the eye causes sorrow, but a chattering fool will fall.

In the multitude of words there is no lack of disobedience, but he who restrains his lips does wisely.

A righteous person is delivered out of trouble, and the wicked takes his place.

Whoever loves correction loves knowledge, but he who hates reproof is stupid.

He who goes about as a tale-bearer reveals secrets; therefore don’t keep company with him who opens wide his lips.

to make their land an astonishment, and a perpetual hissing. Everyone who passes by it will be astonished, and shake his head.

For wasn’t Israel a derision to you? Was he found among thieves? For as often as you speak of him, you shake your head.

the lips of those that rose up against me, and their plots against me all day long.

There is cursing, lying, murder, stealing, and committing adultery; they break boundaries, and bloodshed causes bloodshed.

It will happen that all those who look at you will flee from you, and say, ‘Nineveh is laid waste! Who will mourn for her?’ Where will I seek comforters for you?”

They told him, “He will miserably destroy those miserable men, and will lease out the vineyard to other farmers, who will give him the fruit in its season.”

“He said to him, ‘Out of your own mouth I will judge you, you wicked servant! You knew that I am an exacting man, taking up that which I didn’t lay down, and reaping that which I didn’t sow.

If anyone among you thinks himself to be religious while he doesn’t bridle his tongue, but deceives his heart, this man’s religion is worthless.

Abram said to the king of Sodom, “I have lifted up my hand to Yahweh, God Most High, possessor of heaven and earth,

Reuben returned to the pit, and saw that Joseph wasn’t in the pit; and he tore his clothes.

When he saw her, he tore his clothes, and said, “Alas, my daughter! You have brought me very low, and you are one of those who trouble me; for I have opened my mouth to Yahweh, and I can’t go back.”

The king lamented for Abner, and said, “Should Abner die as a fool dies?

You will destroy those who speak lies. Yahweh abhors the bloodthirsty and deceitful man.

Everyone lies to his neighbor. They speak with flattering lips, and with a double heart.

Let the lying lips be mute, which speak against the righteous insolently, with pride and contempt.

Many are the afflictions of the righteous, but Yahweh delivers him out of them all.

He has brought on them their own iniquity, and will cut them off in their own wickedness. Yahweh, our God, will cut them off.

that the wise man may hear, and increase in learning; that the man of understanding may attain to sound counsel:

you are trapped by the words of your mouth; you are ensnared with the words of your mouth.

The wise in heart accept commandments, but a chattering fool will fall.

The tongue of the wise commends knowledge, but the mouth of fools gush out folly.

A man who isolates himself pursues selfishness, and defies all sound judgment.

The heart of the discerning gets knowledge. The ear of the wise seeks knowledge.

He who gets wisdom loves his own soul. He who keeps understanding shall find good.

It is a snare to a man to make a rash dedication, then later to consider his vows.

Like the legs of the lame that hang loose, so is a parable in the mouth of fools.

It is good that you should take hold of this. Yes, also don’t withdraw your hand from that; for he who fears God will come out of them all.

The words of a wise man’s mouth are gracious; but a fool is swallowed by his own lips.

Their tongue is a deadly arrow. It speaks deceit. One speaks peaceably to his neighbor with his mouth, but in his heart, he waits to ambush him.

Therefore king Darius signed the writing and the decree.

The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.

“Again, the Kingdom of Heaven is like treasure hidden in the field, which a man found, and hid. In his joy, he goes and sells all that he has, and buys that field.

He said to them, “Therefore every scribe who has been made a disciple in the Kingdom of Heaven is like a man who is a householder, who brings out of his treasure new and old things.”

He swore to her, “Whatever you shall ask of me, I will give you, up to half of my kingdom.”
