Matthew 24:36-42

36But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only. 37But as the days of Noah were, so shall also the coming of the Son of man be. 38For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark, 39And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be. 40Then shall two be in the field; the one shall be taken, and the other left. 41Two women shall be grinding at the mill; the one shall be taken, and the other left.

42Watch therefore: for ye know not what hour your Lord doth come.
