Luke 12:35-39

35Let your loins be girded about, and your lamps burning; 36and be ye yourselves like unto men looking for their lord, when he shall return from the marriage feast; that, when he cometh and knocketh, they may straightway open unto him. 37Blessed 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 sit down to meat, and shall come and serve them. 38And if he shall come in the second watch, and if in the third, and find them so, blessed are those servants. 39But know this, that if the master of the house had known in what hour the thief was coming, he would have watched, and not have left his house to be broken through.
