Matthew 24:36

περὶ δὲ τῆς ἡμέρας ἐκείνης καὶ τῆς ὥρας, of that day and hour. The reference is to the coming of the Son of Man, the expression throughout the N. T. having the value of an “indisputable fixed terminus technicus,” Weiffenbach, Wiederkunftsgedanke, p. 157. οὐδεὶς οἶδεν, no one knows, a statement made more emphatic by application to the angels of heaven, and even to the Son (οὐδὲ ὁ υἱός). The meaning is not that Jesus disclaims even for Himself knowledge of the precise day, month, or year of what in Matthew 24:34 He has declared will happen within the present generation; whether, e.g., the crisis of the war would be in 69 or 70 A.D. That is too trivial a matter to be the subject of so solemn a declaration. It is an intimation that all statements as to the time of the παρουσία must be taken in a qualified sense as referring to a subject on which certain knowledge is not attainable or even desirable. It looks like Jesus correcting Himself, or using two ways of speaking, one for comfort (it will be soon), and one for caution (it may not be so soon as even I think or you expect). His whole manner of speaking concerning the second advent seems to have two faces; providing on the one hand for the possibility of a Christian era, and on the other for an accelerated Parusia.
