Wednesday Night Services

What happened when Jesus "ascended on high?" Paul quotes a verse from Psalms 68 in discussing this, and its use he ties two other events into the ascension of Jesus. What are these events and what light do the shed on what happened? The verse tells us that "He led captivity captive," so what did Jesus lead captive? Was it something the cross gave Him victory over or was there another victory. I've been spending a good bit of today to get an understanding of the other two events that using Psalm 68 brings into this, and also looking at the ascension of Jesus. There were two, so which one is in mind here? The first after he rose from the dead, or the second from the mount of Olives? There is a good bit of teaching about Jesus leading captivity captive, but if our understanding is wrong, so are our conclusions.
