'Marching' in the Bible

When however they are marching you along under arrest, do not be anxious beforehand about what you are to say, but speak what is given you when the time comes; for it will not be you who speak, but the Holy Spirit.

Or what king, marching to encounter another king in war, does not first sit down and deliberate whether he is able with ten thousand men to meet the one who is advancing against him with twenty thousand?
