James 1:19-21 My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, for man’s anger does not bring about the righteous life that God desires. Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you.
Matt 5:21-24 “You have heard that it was said to the people long ago, ‘Do not murder, and anyone who murders will be subject to judgment.’ But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, ‘Raca,’ is answerable to the Sanhedrin. But anyone who says, ‘You fool!’ will be in danger of the fire of hell.
“Therefore, if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there in front of the altar. First go and be reconciled to your brother; then come and offer your gift.
