The Spirit will give words in the hour of trial.

²⁰For it is not ye that speak, but the Spirit of your Father which speaketh in you.

¹¹But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost.

¹²For the Holy Ghost shall teach you in the same hour what ye ought to say.
