Matthew 24:41

For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ship,

and they didn’t know until the flood came and took them all away, so will the coming of the Son of Man be.

Then two men will be in the field: one will be taken and one will be left.

Watch therefore, for you don’t know in what hour your Lord comes.

But know this, that if the master of the house had known in what watch of the night the thief was coming, he would have watched, and would not have allowed his house to be broken into.

Therefore also be ready, for in an hour that you don’t expect, the Son of Man will come.
