John Gill Commentary Ezekiel 36:33

"Thus saith the Lord Jehovah: In the day that I cleanse you from all your iniquities, I will cause the cities to be inhabited, and the waste places shall be builded." — Ezekiel 36:33 (ASV)

Thus says the Lord God, in the day that I shall have cleansed you from all your iniquities By the free and full pardon of them; by sprinkling clean water on them, the blood of Christ on their consciences; and by applying the righteousness of Christ to them for their justification; as well as by creating clean hearts in them, for their sanctification; and enabling them by grace to escape and abstain from the pollutions of the world: I will also cause you to dwell in the cities; that is, of Judea, which, as well as Jerusalem, shall be rebuilt and inhabited, as follows: and the wastes shall be builded: such cities and towns as lay in ruins: temporal prosperity shall go along with or follow spiritual blessings to the people of the Jews at their conversion; or they shall dwell in the churches of Christ, which are as cities compact together, well regulated, and where Jews and Gentiles at this time will be fellow citizens.
