Verses on maintaining the peace:
Be completely humble and gentle; be patient, bearing with one another in love. 3 Make every effort to keep the unity of the Spirit through the bond of peace (Ephesians 4:2-3).
Better a patient person than a warrior,
one with self-control than one who takes a city (Proverbs 16:32).
A worthless man digs up evil,
While his words are like scorching fire.
28 A perverse man spreads strife,
And a slanderer separates intimate friends. (Proverbs 16:27-28)
The words of a whisperer are like dainty morsels,
And they go down into the innermost parts of the body. (Proverbs 18:8)
Refrain from anger and turn from wrath;
do not fret—it leads only to evil (Psalms 37:8).
Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. 32 Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you (Ephesians 4:31-32).
But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips (Colossians 3:8).
A gentle answer turns away wrath,
But a harsh word stirs up anger. (Proverbs 15:1)
By forbearance a ruler may be persuaded,
And a soft tongue breaks the bone. (Proverbs 25:15)
Before destruction the heart of man is haughty,
But humility goes before honor. (Proverbs 18:12)
He who conceals a transgression seeks love,
But he who repeats a matter separates intimate friends. (Proverbs 17:19)
The first to plead his case seems right,
Until another comes and examines him. (Proverbs 18:17)
He who gives an answer before he hears,
It is folly and shame to him. (Proverbs 18:13)
When there are many words, transgression is unavoidable,
But he who restrains his lips is wise. (Proverbs 10:19)
A fool does not delight in understanding,
But only in revealing his own mind. (Proverbs 18:2)
Argue your case with your neighbor,
And do not reveal the secret of another,
10 Or he who hears it will reproach you,
And the evil report about you will not [e]pass away. (Proverbs 25:9-10)
Verses on righteousness:
Like a bad tooth and an unsteady foot
Is confidence in a faithless man in time of trouble. (Proverbs 25:19)
Like a trampled spring and a [t]polluted well
Is a righteous man who gives way before the wicked. (Proverbs 25:26)
To show partiality to the wicked is not good,
Nor to thrust aside the righteous in judgment. (Proverbs 18:5)
