The September 2015 broadcast had David Splane explain Matthew 24:34 “Truly, I say to you, this generation will not pass away until all these things take place”. His explanation of this scripture was by means of a chart to indicate an overlapping generation.
Let's make this case perfectly sPlane -- Matt 24:34 had a clear omission, a word that was available in those days, overlapping.
It should have said, "this overlapping generation will not pass away until all these things take place."
An obvious blunder on the part of Matthew in the taking of Jesus' dictation -- or Jesus, in dictating. But we certainly can't blame Jesus, now can we? That would be blasphemy.
