Luke 12:35-38

35Let your loins be girded about, and lamps burning;

36and ye like men who wait their own lord whenever he may leave the wedding, that when he comes and knocks, they may open to him immediately.

37Blessed are those bondmen whom the lord [on] coming shall find watching; verily I say unto you, that he will gird himself and make them recline at table, and coming up will serve them.

38And if he come in the second watch, and come in the third watch, and find [them] thus, blessed are those [bondmen].
