Matthew 5:9-12
Blessed are the peacemakers: for they shall be called children of God.
Blessed are they that suffer persecution for justice' sake: for theirs is the kingdom of heaven.
Blessed are ye when they shall revile you, and persecute you, and speak all that is evil against you, untruly, for my sake:
Be glad and rejoice, for your reward is very great in heaven. For so they persecuted the prophets that were before you.
