And they shall go forth, and look upon the {k} carcases of the men that have transgressed against me: for their {l} worm shall not die, neither shall their fire be quenched; and they shall be an abhorrence {m} to all flesh.

(k) As he who declared the happiness that will be within the Church for the comfort of the godly, so does he show what horrible calamity will come to the wicked, that are out of the Church.

(l) Meaning, a continual torment of conscience, which will always gnaw them, and never permit them to be at rest, Mr 9:44.

(m) This is the just recompense for the wicked, who contemning God and his word, will be by God's just judgments abhorred by all his creatures.

Jamieson-Fausset-Brown Bible Commentary

24. go forth, and look-as the Israelites looked at the carcasses of the Egyptians destroyed at the Red Sea (Ex 14:30; compare Isa 26:14-19; Ps 58:10; 49:14; Mal 4:1-3).

carcasses, &c.-(Isa 66:16), those slain by the Lord in the last great battle near Jerusalem (Zec 12:2-9; 14:2-4); type of the final destruction of all sinners.

worm . not die-(Mr 9:44, 46, 48). Image of hell, from bodies left unburied in the valley of Hinnom (whence comes Gehenna, or "hell"), south of Jerusalem, where a perpetual fire was kept to consume the refuse thrown there (Isa 30:33). It shall not be inconsistent with true love for the godly to look with satisfaction on God's vengeance on the wicked (Re 14:10). May God bless this Commentary, and especially its solemn close, to His glory, and to the edification of the writer and the readers of it, for Jesus' sake!

Matthew Henry's Concise Commentary

66:19,20, set forth the abundance of means for conversion of sinners. These expressions are figurative, and express the plentiful and gracious helps for bringing God's elect home to Christ. All shall be welcome; and nothing shall be wanting for their assistance and encouragement. A gospel ministry shall be set up in the church; they would have solemn worship before the Lord. In the last verse the nature of the punishment of sinners in the world to come is represented. Then shall the righteous and wicked be separated. Our Saviour applies this to the everlasting misery and torment of impenitent sinners in the future state. To the honour of that free grace which thus distinguishes them, let the redeemed of the Lord, with humility, and not without holy trembling, sing triumphant songs. With this affecting representation of the opposite states of the righteous and wicked, characters which include the whole human race, Isaiah concludes his prophecies. May God grant, for Christ's sake, that our portion may be with those who fear and love his name, who cleave to his truths, and persevere in every good work, looking to receive from the Lord Jesus Christ the gracious invitation, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world.
