^28-30 “If any of you wanted to build a tower, wouldn’t he first sit down and work out the cost of it, to see if he can afford to finish it? Otherwise, when he has laid the foundation and found himself unable to complete the building, everyone who sees it will begin to jeer at him, saying, ‘This is the man who started to build a tower but couldn’t finish it!’

^31-33 “Or, suppose there is a king who is going to war with another king, doesn’t he sit down first and consider whether he can engage the twenty thousand of the other king with his own ten thousand? And if he decides he can’t, then, while the other king is still a long way off, he sends messengers to him to ask for conditions of peace. So it is with you; only the man who says goodbye to all his possessions can be my disciple.
