Matthew 24:36-44 - The Unknown Day And Hour
36 "No one knows when that day or hour will come not the angels in heaven, nor the Son, but only the Father, 37 because just as it was in the days of Noah, so it will be when the Son of Man comes. 38 In those days before the flood, people were eating and drinking, marrying and giving in marriage right up to the day when Noah went into the ark. 39 They were unaware of what was happening until the flood came and swept all of them away. That's how it will be when the Son of Man comes. 40 At that time, two people will be in the field. One will be taken, and one will be left behind. 41 Two women will be grinding grain at the mill. One will be taken, and one will be left behind. 42 "So keep on watching, because you don't know on what day your Lord is coming. 43 But be sure of this: if the owner of the house had known when during the night the thief would be coming, he would have stayed awake and not allowed his house to be broken into. 44 So you, too, must be ready, because the Son of Man will come at an hour you are not expecting."
32 "No one knows when that day or hour will come not the angels in heaven, not the Son, but only the Father. 33 Be careful! Watch out! Because you don't know when the time will come. 34 It's like a man who went on a trip. As he left home, he put his servants in charge, each with his own work, and he ordered the doorkeeper to be alert. 35 So keep on watching, because you don't know when the master of the house is coming whether in the evening, at three o'clock in the morning, or at dawn. 36 Otherwise, he may come suddenly and find you asleep. 37 I'm telling you what I'm telling everyone: Be alert!"
