“I will increase them.” The prophecies of the future Millennial Kingdom include all Israel being filled with people. This will be due in large part to the number of righteous people who will be in the first resurrection, the Resurrection of the Righteous, and also because the natural people allowed into the Kingdom from the Sheep and Goat Judgement will multiply greatly.
[For more on the Millennial Kingdom, see Appendix 3, “Christ’s Future Kingdom on Earth.” For more on the Sheep and Goat Judgment, see Matt. 25:31-46 and commentary on Matt. 25:32].
