Matthew 10:19-20 (KJV)
But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. For it is not ye that speak, but the Spirit of your Father which speaketh in you.
Mark 13:11 (KJV)
But 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.
Luke 12:11-12 (KJV)
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: For the Holy Ghost shall teach you in the same hour what ye ought to say.
"Holy Spirit" != "Spirit of the Father"and the Synoptics are in perfect (or near-perfect) agreement. It doesn't seem a very open question; "Yes!" seems the only possible answer. – Jon Ericson♦ Feb 20 at 20:40
