Luke 12:11 in the King James Version
And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say:
Context
10 Everyone who speaks a word against the Son of Man will be forgiven, but those who blaspheme against the Holy Spirit will not be forgiven.
11 When they bring you before the synagogues, the rulers, and the authorities, don’t be anxious how or what you will answer or what you will say;
12 for the Holy Spirit will teach you in that same hour what you must say.”
