In context
11There will be great earthquakes, and famines and plagues in place after place; there will be terrors, and great signs from heaven. 12But before all this they will lay hands on you and persecute you. They will hand you over to the synagogues and prisons, and you will be led before kings and governors for the sake of my name. 13And it will give you your chance to bear witness. 14So settle it in your hearts not to rehearse your defense beforehand, 15for I will give you words and wisdom that none of your opponents will be able to resist or contradict.
