Matthew 24:40

37 And as [were] the days of Noah, so shall be the coming of the Son of man.

38 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 ark,

39 and they knew not until the flood came, and took them all away; so shall be the coming of the Son of man.

40 Then shall two man be in the field; one is taken, and one is left:

41 two women [shall be] grinding at the mill; one is taken, and one is left.

42 Watch therefore: for ye know not on what day your Lord cometh.

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