The Olivet Discourse or Olivet prophecy is a biblical passage found in the Synoptic Gospels in Matthew 24 and 25, Mark 13, and Luke 21. It is also known as the Little Apocalypse because it includes the use of apocalyptic language, and it includes Jesus's warning to his followers that they will suffer tribulation and persecution before the ultimate triumph of the Kingdom of God.

Then Jesus identifies "the beginnings of birth pains":
