Matthew 24:36-44 - The Unknown Day And Hour
36 But no one knows of that day and hour, not even the angels of heaven, but my Father only. 37 "As the days of Noah were, so will 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 ship, 39 and they didn't know until the flood 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 will be taken and one will be left; 41 two women grinding at the mill, one will be taken and one will be left. 42 Watch therefore, for you don't know in what hour your Lord comes. 43 But know this, that if the master of the house had known in what watch of the night the thief was coming, he would have watched, and would not have allowed his house to be broken into. 44 Therefore also be ready, for in an hour that you don't expect, the Son of Man will come.
32 But of that day or that hour no one knows, not even the angels in heaven, nor the Son, but only the Father. 33 Watch, keep alert, and pray; for you don't know when the time is. 34 "It is like a man, traveling to another country, having left his house, and given authority to his servants, and to each one his work, and also commanded the doorkeeper to keep watch. 35 Watch therefore, for you don't know when the lord of the house is coming, whether at evening, or at midnight, or when the rooster crows, or in the morning; 36 lest coming suddenly he might find you sleeping. 37 What I tell you, I tell all: Watch."
