Matthew 5:21-24New International Version (NIV)

Murder

²¹ “You have heard that it was said to the people long ago, ‘You shall not murder,^[a] and anyone who murders will be subject to judgment.’ ²² But I tell you that anyone who is angry with a brother or sister^[b][c] will be subject to judgment. Again, anyone who says to a brother or sister, ‘Raca,’^[d] 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, ²⁴ leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift.
