Luke 12:40

38 Even if he comes in the second or third watch of the night and finds them alert, those servants will be blessed.

39 But understand this: If the homeowner had known at what hour the thief was coming, he would not have let his house be broken into.

You also must be ready, because the Son of Man will come at an hour you do not expect.”

41 “Lord,” said Peter, “are You addressing this parable to us, or to everyone else as well?”

42 And the Lord answered, “Who then is the faithful and wise manager, whom the master puts in charge of his servants to give them their portion at the proper time?

Do read the surrounding verses too, because the context often says more than a single verse.
