Isaiah 4:3

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:

Ver. 3. He that is left in Zion.] See Isaiah 4:2 .

Shall be called holy.] Heb., Holy shall be said to him or of him: he shall have the name and note of a saint, the comfort and the credit of it. Christ's holiness shall be both imputed and imparted unto them: he shall both expiate their sins and heal their natures, pay their debts, and give them a stock of grace and holiness, so that men shall call them a "holy people." Isa 62:12

Even every one that is written among the living.] Written in God's book of life, which is matter of greater joy than to have the devils subdued unto us; Luk 10:17 for a man may cast out devils, and yet be himself cast to the devil; Mat 7:22-23 but in God's book of life there are no blots, no crossings out, but "as many as are ordained to eternal life believe," and the same are "kept as in a garrison by the power of God through faith unto salvation." 1Pe 1:4 The prophet seemeth here to allude to that custom in Jerusalem of enrolling the names of all the citizens. Psa 87:6 Christ Jesus is the Master of the Rolls in heaven, Rev 13:8 wherein none are recorded but such as are designed "to glory and virtue." 1Pe 1:2 2Th 2:13 All others are said to be "dead in trespasses and sins," Eph 2:1 and to be "written in the earth." Jer 17:13 Those priests that could not produce their genealogy were cashiered by the Tirshatha: Ezr 2:63 so shall those one day be by Christ whose names are not found written among the living in Jerusalem.
