Matthew 24:36-44 - The Unknown Day And Hour
36 And concerning that day and hour, none know, nor the messengers of the heavens, except my Father only. 37 And as the days of Noe, so shall be the arrival of the Son of man. 38 For as they were in the days of the inundation, eating and drinking, marrying and giving in marriage, until the day Noe came into the ark, 39 And knew not till the inundation came, and took them all away; so also shall be the arrival of the Son of man. 40 Then shall be two in the field; one shall be taken, and one is let go; 41 Two grinding in the mill; one shall be taken, and one let go. 42 Watch therefore; for ye know not what hour your Lord comes. 43 But know this, that if the master of the house had known what watch the thief comes, he had watched, and would not have suffered his house to be undermined. 44 Therefore be ye also prepared: for what hour ye think not, the Son of man comes.
32 And concerning that day and hour none knows, nor the messengers in heaven, neither the Son, but the Father. 33 See, watch and pray: for ye know not when the time is. 34 As a man travelling, having left his house, and having given power to his servants, and to each his work, and he commanded the guard of the door that he should watch. 35 Watch therefore: for ye know not when the lord of the house comes, at eve, or midnight, or cock-crowing, or morning. 36 Lest having come suddenly he find you sleeping. 37 And what I say to you, I say to all, Watch ye.
