Matthew 5:22-24

But I tell you, don’t be angry with anyone. If you are angry with others, you will be judged. And if you insult someone, you will be judged by the high court. And if you call someone a fool, you will be in danger of the fire of hell. “So, what if you are offering your gift at the altar and remember that someone has something against you? Leave your gift there and go make peace with that person. Then come and offer your gift.
