Matthew 24:36-44 - The Unknown Day And Hour
36 As to the day and hour, that no one knows, not even the angels of heaven, but the father only. 37 as the days of Noe were, so shall also the advent of the son of man be. 38 for as at the time that usher'd in the deluge, they were eating and drinking, marrying themselves and their children, till the day that Noe entred into the ark, 39 having no thoughts of the flood till it came, and swept them all away; so shall also the advent of the son of man be. 40 of two persons, who shall be then in the field, one shall be taken, and the other left. 41 two women shall be grinding at the mill, the one shall be taken, and the other left. 42 watch therefore, for ye know not at what hour your Lord shall come. 43 but this you conceive, that if a man knew at what hour of the night the thief would come, he would set a watch, and not suffer his house to be broke open. 44 therefore be ye also prepar'd: for the son of man may come at an hour you least expect.
32 as to the day and hour, that no one knows, neither the angels in heaven, nor even the son; but the father only. 33 be circumspect, be vigilant, and devout: because you are uncertain when that time will be. 34 when a man travels into foreign parts, he leaves his goods in charge to his servants, he appoints to every one his task, and orders the porter to be vigilant, 35 watch ye therefore (for you don't know when the master of the house will return; whether at evening, or at midnight, or at the cock-crowing, or in the morning) 36 for fear by his sudden return he should surprize you sleeping. 37 what I say to you, I say to all, be vigilant.
