This vision of Zechariah 2 speaks of the day when God in Christ will restore both - during the Millennial Kingdom. The nation of Israel, and Jerusalem itself. This vision speaks to fact that Jerusalem would have a large population, and---God Himself will physically protect Israel from all harm. Two great affirmations are in this third vision- Our Lord's return will be glorious -2-1-9- and Our Lord's future blessings will be glorious -2-10-13-.
