Matthew 24:36-44

But concerning that day and hour, no one knows, not even the Angels of the heavens, but only the Father. And just as in the days of Noah, so also will be the advent of the Son of man. For it will be just as it was in the days before the flood: eating and drinking, marrying and being given in marriage, even until that day when Noah entered into the ark. And they did not realize it, until the flood came and took them all away. So also will the advent of the Son of man be. Then two men will be in a field: one will be taken up, and one will be left behind. Two women will be grinding at a millstone: one will be taken up, and one will be left behind. Therefore, be vigilant. For you do not know at what hour your Lord will return. But know this: if only the father of the family knew at what hour the thief would arrive, he would certainly keep vigil and not permit his house to be broken into. For this reason, you also must be prepared, for you do not know at what hour the Son of man will return.
