The Apostle Paul now tells us about the purpose of pastors and other office bearers exercising teaching functions in the church of Jesus Christ, and he quotes from Psalm 68:18 to show that these offices are rooted in prophecy: ‘Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.’ God speaks through David in that psalm, and it is a psalm about victories.
