The Two Witnesses
The one who conquers and who keeps my works until the end, to him I will give authority over the nations, and he will rule them with a rod of iron, as when earthen pots are broken in pieces, even as I myself have received authority from my Father.
Christ refers here to Psalm 2. It had been fulfilled in the “head” at His ascension. At this point, it was yet to be fulfilled in the “body.”
