Matthew 24:36

That day and hour. That is, of His coming and of the end of the world (see on v. 3). Those who are tempted to calculate precisely how many years remain before the appearance of Christ would do well to ponder the counsel here given, and also that of Acts 1:7. It is the privilege and duty of Christians to remain alert, to watch for the signs of His return, and to know when His coming is near (see on v. 33).

Not the angels. Textual evidence favors (cf. p. 146) adding the words, “nor the Son.” In Mark 13:32 textual evidence unanimously supports this reading. Commentators have generally understood this to mean that as a man on earth Christ voluntarily limited His knowledge and power to the capacities of human beings in order that His own perfect life might be an example of how we should live, and that His ministry might be a pattern we could follow, aided by the same divine guidance and help that were His (see on Luke 2:52).

My father only. See on Acts 1:7.
