Proverbs 6:16-19 

There are six things that the Lord hates, seven that are an abomination to him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.

Leviticus 19:17 

“You shall not hate your brother in your heart, but you shall reason frankly with your neighbor, lest you incur sin because of him.

1 John 2:9 

Whoever says he is in the light and hates his brother is still in darkness.

1 Corinthians 13:4-7 

Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.

Ephesians 4:29  

Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.

Proverbs 15:1 

A soft answer turns away wrath, but a harsh word stirs up anger.

1 John 2:11 

But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
