Lk 12: 35-38
‘See that you have your belts done up and your lamps lit. Be like people waiting for their master to return from the wedding feast, ready to open the door as soon as he comes and knocks. Blessed those servants whom the master finds awake when he comes. In truth I tell you, he will do up his belt, sit them down at table and wait on them. It may be in the second watch that he comes, or in the third, but blessed are those servants if he finds them ready.‘
