And it came to pass, as they walked in the way, that a certain man said to him: I will follow thee whithersoever thou goest.  Jesus said to him: The foxes have holes, and the birds of the air nests; but the Son of man hath not where to lay his head.  But he said to another: Follow me. And he said: Lord, suffer me first to go, and to bury my father.  And Jesus said to him: Let the dead bury their dead: but go thou, and preach the kingdom of God.
 And another said: I will follow thee, Lord; but let me first take my leave of them that are at my house.  Jesus said to him: No man putting his hand to the plough, and looking back, is fit for the kingdom of God.Luke 9:57-61
