Matthew 5:22-24

22But I tell you that anyone who is angry with a brother or sister The Greek word for brother or sister (adelphos) refers here to a fellow disciple, whether man or woman; also in verse 23. Some manuscripts brother or sister without cause will be subject to judgment. Again, anyone who says to a brother or sister, ‘Raca,’ An Aramaic term of contempt is answerable to the court. And anyone who says, ‘You fool!’ will be in danger of the fire of hell. 23“Therefore, if you are offering your gift at the altar and there remember that your brother or sister has something against you,

24leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift.
