Thematic Bible: King going to war

Or what king, planning to engage another king in war, will not first sit down and evaluate whether he will be able, with ten thousand [soldiers], to defeat someone who attacks him with twenty thousand [soldiers]? Or maybe, while the enemy is still a long way off, he will send representatives to ask for peace terms. So therefore, every one of you who does not say 'goodbye' to everything he owns, cannot be my disciple.
