Matthew 24:41

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.

43 But be certain of this, that if the master of the house had had knowledge of the time when the thief was coming, he would have been watching, and would not have let his house be broken into.

44 Be ready then; for at a time which you have no thought of the Son of man will come.
