What verse range in Matthew 24 covers the first three and a half years of the tribulation?
The first three and a half years of the tribulation are covered by Matthew 24:5 through 13, or more precisely 5 through 12 according to the transcript. Verse 15 marks the midpoint, while verses 13 and 14 continue on to the end.
Les explains that beginning in verse 15, the passage is at the midpoint of the tribulation. He states that the first three and a half years have been culminated by the events in verses 5 through 13, or really 12, because verses 13 and 14 go all the way on to the end. So the first half of the tribulation is described in Matthew 24:5-13, with verse 15 introducing the midpoint.
