Matthew 10:19
When they deliver you over, do not be anxious how you are to speak or what you are to say, for what you are to say will be given to you in that hour. The do not be anxious in the face of persecution echoes the do not be anxious about provision (6:25) — both forms of anxiety are addressed by the same principle: the Father provides. The specific provision promised here is the speech to give in the moment of trial. Acts 4:8–13 records Peter filled with the Holy Spirit speaking to the rulers and elders with a boldness that amazed them. The Spirit who provides the speech in the trial moment is the same Spirit who empowers the mission.
