Verses 33-36 describe the effect of Israel's restored prosperity on the surrounding nations.
36:25-38 Water is an emblem of the cleansing our polluted souls from sin. But no water can do more than take away the filth of the flesh. Water seems in general the sacramental sign of the sanctifying influences of the Holy Ghost; yet this is always connected with the atoning blood of Christ. When the latter is applied by faith to the conscience, to cleanse it from evil works, the former is always applied to the powers of the soul, to purify it from the pollution of sin. All that have an interest in the new covenant, have a new heart and a new spirit, in order to their walking in newness of life. God would give a heart of flesh, a soft and tender heart, complying with his holy will. Renewing grace works as great a change in the soul, as the turning a dead stone into living flesh. God will put his Spirit within, as a Teacher, Guide, and Sanctifier. The promise of God's grace to fit us for our duty, should quicken our constant care and endeavour to do our duty. These are promises to be pleaded by, and will be fulfilled to, all true believers in every age.
Thus saith 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.
