Matthew 24:36-44 - The Unknown Day And Hour
36 "But no one knows about that day and hour, not even the angels in heaven, nor the Son, but only the Father. 37 And as were the days of Noah, so will be the coming of the Son of man. 38 For just as in the days before the deluge they were eating and drinking, marrying and giving in marriage, until the very day when Noah entered the ark, 39 nor did they know until the deluge came and swept them away; so will be the coming of the son of man. 40 At that time there will be two men in the field; one will be taken, and one will be left. 41 Two women will be grinding at the mill; one will be taken and the other left. 42 Keep guard then, for you do not know the day on which your Master is coming. 43 But know this, that if the master of the house had known in what watch the thief was coming, he would have been on his guard, and would not have allowed his house to be broken into. 44 Therefore you also must be ready, for in an hour when you do not expect him, the Son of man is coming.
32 But concerning that day or that hour no one knows, not even the angels in heaven, 33 nor the Son, but only the Father. 34 Take heed! Awake! for you never know the time. As a man gone abroad and leaving his house gives authority to his slaves, to each his task; and orders the porter to keep watch; 35 keep watch then, for you do not know when the master of the house is coming??n the evening, at midnight, at cockcrow, or in the morning??36 lest he should come unexpectedly and find you sleeping; 37 and what I say to you, I say to all. Be awake and on guard."
