Mark 13:11 in the World English Bible
When they lead you away and deliver you up, don’t be anxious beforehand or premeditate what you will say, but say whatever will be given you in that hour. For it is not you who speak, but the Holy Spirit.
Context
10 And the gospel must first be published among all nations.
11 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.
12 Now 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.
