Mark 13:9-11

But take ye heed to yourselves: for they shall deliver you up to councils; and in synagogues shall ye be beaten; and before governors and kings shall ye stand for my sake, for a testimony unto them. And the gospel must first be preached unto all the nations. And when they lead you to judgment, and deliver you up, be not anxious beforehand what ye shall speak: but whatsoever shall be given you in that hour, that speak ye; for it is not ye that speak, but the Holy Spirit.
