"You yourselves must watch out. You will be arrested and taken to court. You will be beaten in the synagogues; you will stand before rulers and kings for my sake to tell them the Good News. 1
But before the end comes, the gospel must be preached to all peoples.
And when you are arrested and taken to court, do not worry ahead of time about what you are going to say; when the time comes, say whatever is then given to you. For the words you speak will not be yours; they will come from the Holy Spirit.
Men will hand over their own brothers to be put to death, and fathers will do the same to their children. Children will turn against their parents and have them put to death.
Everyone will hate you because of me. But whoever holds out to the end will be saved. 2
