Christ's session in heaven foretold
And that God the Father of all would bring Christ to heaven after He had raised Him from the dead, and would keep Him there until He has subdued His enemies the devils, and until the number of those who are foreknown by Him as good and virtuous is complete, on whose account He has still delayed the consummation— hear what was said by the prophet David. These are his words: “The Lord said unto My Lord, Sit at My right hand, until I make Your enemies Your footstool. The Lord shall send to You the rod of power out of Jerusalem; and rule You in the midst of Your enemies.
With You is the government in the day of Your power, in the beauties of Your saints: from the womb of morning have I begotten You.” That which he says, “He shall send to You the rod of power out of Jerusalem,” is predictive of the mighty word, which His apostles, going forth from Jerusalem, preached everywhere; and though death is decreed against those who teach or at all confess the name of Christ, we everywhere both embrace and teach it. And if you also read these words in a hostile spirit, you can do no more, as I said before, than kill us; which indeed does no harm to us, but to you and all who unjustly hate us, and do not repent, brings eternal punishment by fire.
