Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. - Ephesians 4:29
For the wicked boasts of his heart’s desire; he blesses the greedy and renounces the Lord. The wicked in his proud countenance does not seek God; God is in none of his thoughts. His ways are always prospering; Your judgments are far above, out of his sight; as for all his enemies, he sneers at them. He has said in his heart, “I shall not be moved; I shall never be in adversity.” His mouth is full of cursing and deceit and oppression; under his tongue is trouble and iniquity. He sits in the lurking places of the villages; in the secret places he murders the innocent; his eyes are secretly fixed on the helpless. - Psalm 10:3-8
Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my strength and my Redeemer. - Psalm 19:14
An oracle within my heart concerning the transgression of the wicked: There is no fear of God before his eyes. For he flatters himself in his own eyes, when he finds out his iniquity and when he hates. The words of his mouth are wickedness and deceit; He has ceased to be wise and to do good. He devises wickedness on his bed; He sets himself in a way that is not good; he does not abhor evil. - Psalm 36:1-4
The mouth of the righteous speaks wisdom, and his tongue talks of justice. The law of his God is in his heart; - Psalm 37:30-31a

Listen, for I will speak of excellent things, and from the opening of my lips will come right things; for my mouth will speak truth; wickedness is an abomination to my lips. All the words of my mouth are with righteousness; nothing crooked or perverse is in them. - Proverbs 8:7-8
The hypocrite with his mouth destroys his neighbor, but through knowledge the righteous will be delivered. When it goes well with the righteous, the city rejoices; And when the wicked perish, there is jubilation. By the blessing of the upright the city is exalted, but it is overthrown by the mouth of the wicked. He who is devoid of wisdom despises his neighbor, but a man of understanding holds his peace. - Proverbs 11:9-12
Whoever guards his mouth and tongue keeps his soul from troubles. - Proverbs 21:23

Better not to vow than to vow and not pay. Do not let your mouth cause your flesh to sin, nor say before the messenger of God that it was an error. Why should God be angry at your excuse and destroy the work of your hands? For in the multitude of dreams and many words there is also vanity. But fear God. - Ecclesiastes 5:5-7
“Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit. Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned.” - Matthew 12:33-37
When He had called the multitude to Himself, He said to them, “Hear and understand: not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.” - Matthew 15:10-11
Do you not yet understand that whatever enters the mouth goes into the stomach and is eliminated? But those things which proceed out of the mouth come from the heart, and they defile a man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies. - Matthew 15:17-19
But no man can tame the tongue. It is an unruly evil, full of deadly poison. With it we bless our God and Father, and with it we curse men, who have been made in the similitude of God. Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so. - James 3:8-10
These are grumblers, complainers, walking according to their own lusts; and they mouth great swelling words, flattering people to gain advantage. But you, beloved, remember the words which were spoken before by the apostles of our Lord Jesus Christ: how they told you that there would be mockers in the last time who would walk according to their own ungodly lusts. These are sensual persons, who cause divisions, not having the Spirit. But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit, keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. And on some have compassion, making a distinction; but others save with fear, pulling them out of the fire, hating even the garment defiled by the flesh. Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy, to God our Savior, Who alone is wise, be glory and majesty, dominion and power, both now and forever. Amen. - Jude 1:16-25
I said, “I will guard my ways, lest I sin with my tongue; I will restrain my mouth with a muzzle, while the wicked are before me.” I was mute with silence, I held my peace even from good; and my sorrow was stirred up. My heart was hot within me; while I was musing, the fire burned. Then I spoke with my tongue: “Lord, make me to know my end, and what is the measure of my days, that I may know how frail I am. Indeed, You have made my days as handbreadths, and my age is as nothing before You; certainly every man at his best state is but vapor. Selah Surely every man walks about like a shadow; surely they busy themselves in vain; he heaps up riches, and does not know who will gather them. “And now, Lord, what do I wait for? My hope is in You. - Psalm 39: 1-7
