Mark 13:9-12

9But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. 10And the gospel must first be proclaimed among all nations. 11But when they shall lead you, and deliver you up, be not anxious beforehand what ye shall speak, neither do ye premeditate: but whatever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Spirit. 12Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death.
