This chapter speaks of the new glory of Jerusalem, which is universal in scope. God will speak concerning the events predicted in the preceding chapter. The Servant of God, the Messiah, would not rest until He had accomplished His mission, Isaiah 62:1.
Pett, in his commentary, says the following.
‘Once again salvation and righteousness are paramount. Both go together. There can be no salvation until they are accounted righteous, and that can only be through that salvation. Both go forward hand in hand. Then once righteousness has been imputed, Isaiah 53:11 / Isaiah 4:3, and imparted it will be like a shining brightness, a vivid brightness before them. They will be a fit witness to the glory of Yahweh. Their lights will shine out before men who will see their good works and glorify their Father Who is in Heaven, Matthew 5:16.’
Jerusalem will receive a new name, Isaiah 62:2, after God’s righteousness and glory were seen by all nations and kings, Isaiah 62:2-3. A desolate land is represented as a widow, while an inhabited land is represented as a married woman with children, Isaiah 62:4.
The word ‘Hephzibah’, Isaiah 62:4, literally means, ‘My delight in her’, and the word ‘Beulah’, Isaiah 62:4, literally means ‘married’. In other words, God would delight in the new Jerusalem and the land would be cultivated and productive. As the faithful wife wears the name of her husband, Isaiah 62:5, so Christians, married to Christ, rejoice to wear His Name, Acts 11:26 / Acts 26:28 / 1 Peter 4:16. In other words, the church will be pure.
Here we read that the new Jerusalem is to be established forever. The watchmen were to guard the city and to warn when the enemy was coming, Isaiah 62:6 / Isaiah 56:10. We need faithful watchmen, that is, preachers and elders, in the church today to guard against the enemy, false teachers, Ephesians 4:11-12 / 1 Thessalonians 5:17 / Luke 18:7-8. The walls of this New Jerusalem are called Salvation and Praise, Isaiah 62:6-7 / Isaiah 26:1 / Isaiah 49:16 / Isaiah 60:18.
The hand, Isaiah 62:8, is a symbol of power and the arm of greatness. Based on His greatness and power to fulfil, God is about to commit Himself to a promise that He will fulfil, Isaiah 62:8 / Jeremiah 18:7-10 / Hebrews 6:14-20. They had suffered from the results of their sins, Isaiah 62:8-9, which suffering God had foretold, Deuteronomy 28:33 / Deuteronomy 28:51 / Judges 6:4 / Judges 6:11 / 2 Chronicles 28:18 / Isaiah 16:9.
Here we read that the salvation of God makes new Jerusalem a much-sought place, Isaiah 62:10. The road must be prepared, obstacles must be removed, Isaiah 62:10, and people must be called to come to the Lord, Isaiah 62:11. This is all about being spiritual prepared. Just as the exiles were saved from bondage, the new spiritual Jerusalem was saved from the bondage of sin by the coming of the Redeemer, Isaiah 62:12.
Christ has now come and is ready, willing and able to do all that is to be done to save both Jew and Gentile, Romans 10:11-13 / Romans 3:21-23 / Acts 15:7-9 / Acts 11:12. The citizens of the new Jerusalem will be made holy, Isaiah 62:12 / Revelation 2:24. They will be cleansed by the blood of the Lamb and so, they would never again be forsaken by God, Isaiah 62:12. The redeemed church of the Lord would be composed of people from all nations, Revelation 7:9.
Pett, in his commentary, says the following.
‘Pictured in terms of one huge return from exile of a believing people, something which as far as we know only marginally occurred after the Exile, and never since, we have rather a picture of what would be the result of the coming of Salvation in Jesus, and the spread of the Gospel, with those responding coming to the heavenly equivalent of Zion, the truly free Zion, Galatians 4:26 / Hebrews 12:22, and there being made holy as the redeemed of Yahweh. They will have come home to Zion, Galatians 4:26 / Hebrews 12:22.’
