Recently I was listening to a lecture by Reformed theologian Robert Cara, in which he mentioned how frequently NT writers connect and apply OT Yahweh references to Jesus. A number of examples could be given, but one of the stronger ones is Ephesians 4:7–10, which reads:
7 But grace was given to each one of us according to the measure of Christ's gift. 8 Therefore it says,
“When he ascended on high he led a host of captives,
and he gave gifts to men.”
9 (In saying, “He ascended,” what does it mean but that he had also descended into the lower regions, the earth? 10 He who descended is the one who also ascended far above all the heavens, that he might fill all things.) [ESV]
Paul seems to be clearly talking about Jesus here, talking about his descent to the earth and his subsequent ascent into heaven, paralleling the quoted OT passage. That passage is Psalm 68:18, which reads:
You ascended on high,
leading a host of captives in your train
and receiving gifts among men,
even among the rebellious, that the LORD God may dwell there. [ESV]
From context, the "You" of Psalm 68:18 seems to be Yahweh – the entire chapter interchangeably uses God, Lord, and LORD, and verses 22–26 seem to describe God/Yahweh "leading a host of captives" in more detail.
Thus, the argument goes, Paul is clearly applying an OT description of Yahweh to Jesus, indicating that he believes Jesus is truly the God of the Old Testament (Yahweh).
How do Jehovah's Witness's explain this? Do they interpret Ephesians 4 differently, or Psalm 68 differently, or have some other explanation?
