Ecclesiastes 8:7

Therefore, do you also prepare, since it is just when you are least expecting him that the Son of Man will come.

That servant's master will come on a day when he does not expect him, and at an hour of which he is unaware,

But at midnight a shout was raised--'The Bridegroom is coming! Come out to meet him!'

But as to the times and the moments, there is no need, Brothers, for any one to write to you.
