And this know, that if the owner of the house had known what hour the thief would come, he would have watched, and not have allowed his house to be broken through. Be you therefore ready also: for the Son of man comes at an hour when you think not. Then Peter said unto him, Lord, speak you this parable unto us, or even to all? And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of food at the proper time? Blessed is that servant, whom his lord when he comes shall find so doing. Of a truth I say unto you, that he will make him ruler over all that he has. (Luke 12:39-44)
