The key issue to the structure of Matthew’s Olivet Discourse is the relationship between vv. 9–14 and verse 15ff. I first talked about the disciples’ questions about the sign to the parousia (second coming) and the end of the age, which opens up the discourse. Then I focused on the implications of the conjunction oun (“therefore”) used in verse 15 for the overall structure, especially how it relates to the Antichrist’s great tribulation.
“So [oun] when you see the abomination of desolation–spoken about by Daniel the prophet—standing in the holy place (let the reader understand).” Matt 24:15
