Luke 12:39
King James Version
And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through.
Luke 12:39 in context
Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.
And if he shall come in the second watch, or come in the third watch, and find them so, blessed are those servants.
And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through.
Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.
Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all?
