Luke 12:37-38

Blessed (happy, prosperous, to be admired) are those servants whom the master finds awake and watching when he arrives. I assure you and most solemnly say to you, he will prepare himself to serve, and will have them recline at the table, and will come and wait on them. Whether he comes in the second watch (before midnight), or even in the third (after midnight), and finds them so [prepared and ready], blessed are those servants.
