Verse 28 describes the effect which such a glorious transformation of Israel's character and condition, should produce upon the heathen world. They should recognize from his presence amongst his people, symbolized by the establishment in their midst of his sanctuary, that he had both the power and the will to sanctify them, by making them inwardly as well as outwardly holy; and, recognizing this, they would seek admittance to the congregation and fellowship of God's spiritual Israel.

37:15-28 This emblem was to show the people, that the Lord would unite Judah and Israel. Christ is the true David, Israel's King of old; and those whom he makes willing in the day of his power, he makes to walk in his judgments, and to keep his statutes. Events yet to come will further explain this prophecy. Nothing has more hindered the success of the gospel than divisions. Let us study to keep the unity of the Spirit in the bond of peace; let us seek for Divine grace to keep us from detestable things; and let us pray that all nations may be obedient and happy subjects of the Son of David, that the Lord may be our God, and we may be his people for evermore.And the Heathen shall know that I the Lord do sanctify Israel,.... Or the Gentiles, the converted Gentiles, shall observe and take notice of the gracious dealings of God with his people the Jews; that he calls them with an holy calling; implants principles of grace and holiness in them; separates and consecrates them for his service, and enables them to walk holily, soberly, and righteously:

when my sanctuary shall be in the midst of them for evermore; when his worship shall be set up among them; his Gospel shall be preached unto them, and received by them; and his ordinances administered unto them; and which shall continue till the second coming of Christ.
