Matthew 10:17-20

17But beware of men; for they will deliver you up to sanhedrims, and scourge you in their synagogues;

18and ye shall be brought before rulers and kings for my sake, for a testimony to them and to the nations.

19But when they deliver you up, be not careful how or what ye shall speak; for it shall be given to you in that hour what ye shall speak.

20For ye are not the speakers, but the Spirit of your Father which speaks in you.
