Isaiah 4:3 (KJV) reads as follows: "And it shall come to pass, that he that is left in Zion, and he that remaineth in Jerusalem, shall be called holy, even every one that is written among the living in Jerusalem."

This passage from the Book of Isaiah is a prophetic statement about the future of Zion and Jerusalem. It speaks to a time of purification and restoration for these cities, specifically regarding the remnant of people who will be left after a period of trial and tribulation. The overarching theme of this verse is the belief in the ultimate salvation and holiness of God's chosen people.

The context of Isaiah 4:3 is crucial to understanding its meaning. The preceding chapters in the book of Isaiah contain prophecies of judgment and destruction upon Israel and Judah due to their disobedience and sin. However, amidst the warnings of impending doom, there are also promises of a future restoration and redemption for the faithful remnant.

Isaiah 4:3 is part of a larger passage in which it is suggested that a time will come when the Lord will wash away the filth of the daughters of Zion and cleanse the bloodstains of Jerusalem by a spirit of judgment and a spirit of burning. After this purification, those who remain in Zion and Jerusalem will be called holy, reflecting the righteousness and purity that the Lord will bestow upon them.

The symbolism in Isaiah 4:3 is rich and meaningful. The concept of being "written among the living in Jerusalem" signifies being counted as one of the chosen and righteous individuals who will be spared and saved by the grace of God. This imagery of being recorded among the living in Jerusalem is reminiscent of the Book of Life, a recurring motif in the Bible that represents a register of those who are destined for eternal life.

Furthermore, the use of the term "holy" in this verse conveys the idea of consecration and sanctification. It suggests that the remnant who remain in Zion and Jerusalem will be set apart and dedicated to God, living in accordance with His will and embodying His righteousness. This parallels the broader biblical theme of God's desire for His people to be a holy nation and a royal priesthood (Exodus 19:6).

The passage also carries a theme of hope and restoration. Despite the impending judgment and devastation, Isaiah 4:3 offers the promise of a future in which the remaining inhabitants of Zion and Jerusalem will experience a transformation, being called holy and righteous in the eyes of the Lord. This speaks to the mercy and faithfulness of God, even in the midst of discipline and hardship.

In summary, Isaiah 4:3 is a verse that speaks to the future purification, consecration, and restoration of Zion and Jerusalem. It is a message of hope for the faithful remnant who will be spared by the grace of God and called holy in His sight. The verse is rich in symbolism and carries themes of judgment, salvation, and the ultimate triumph of righteousness. It serves as a reminder of God's unwavering commitment to His people and His promise of redemption for those who remain faithful to Him.
