Matthew 24:39

36 But of that day and hour no one has knowledge, not even the angels in heaven, or the Son, but the Father only.

37 And as were the days of Noah, so will be the coming of the Son of man.

38 Because as in those days before the overflowing of the waters, they were feasting and taking wives and getting married, till the day when Noah went into the ark,

39 And they had no care till the waters came and took them all away; so will be the coming of the Son of man.

40 Then two men will be in the field; one is taken, and one let go;

41 Two women will be crushing grain; one is taken, and one let go.

42 Be watching, then! for you have no knowledge on what day your Lord will come.
