And have left none of then any more there - All that chose had liberty to return; but many remained behind. This promise may therefore refer to a greater restoration, when not a Jew shall be left behind. This, the next verse intimates, will be in the Gospel dispensation.
The purposes of the past dispensation shall be made clear to God‘s people themselves and to the pagan. His judgments were the consequence of their sins; and these sins once abandoned, the favor of their God will return in yet more abundance.
Ezekiel 39:29
Compare Acts 2:17. Peter distinctly appropriates these prophecies (marginal references) to the outpouring of the Holy Spirit on the day of Pentecost, and the inauguration of the Church of Christ by that miraculous event. This was the beginning of the fulfillment. They shall find their consummation when time shall be no more.
