There shall be no more from there an infant of days, nor an old man that hath {z} not filled his days: for the child shall die an hundred years old; but the sinner being {a} an hundred years old shall be accursed.

(z) Meaning, in this wonderful restoration of the Church there would be no weakness of youth, nor infirmities of age, but all would be fresh and flourishing: and this is accomplished in the heavenly Jerusalem, when all sins will cease, and the tears will be wiped away.

(a) By which he shows that the infidels and unrepentant sinners have no part of this benediction.

Wesley's Notes

65:20 An infant - Those that were now children, shall die at a great age. But - Yet none of these things shall be of any advantage to wicked men, but if any of them shall live to be an hundred years old, yet they shall die accursed.

Jamieson-Fausset-Brown Bible Commentary

20. The longevity of men in the first age of the world shall be enjoyed again.

thence-from that time forward.

infant of days-that is, an infant who shall only complete a few days; short-lived.

filled . days-None shall die without attaining a full old age.

child . die . hundred years-that is, "he that dieth an hundred years old shall die a mere child" [Lowth].

sinner . hundred . be accursed-"The sinner that dieth at an hundred years shall be deemed accursed," that is, his death at so early an age, which in those days the hundredth year will be regarded, just as if it were mere childhood, shall be deemed the effect of God's special visitation in wrath [Rosenmuller]. This passage proves that the better age to come on earth, though much superior to the present will not be a perfect state; sin and death shall have place in it (compare Re 20:7, 8), but much less frequently than now.

Matthew Henry's Concise Commentary

65:17-25 In the grace and comfort believers have in and from Christ, we are to look for this new heaven and new earth. The former confusions, sins and miseries of the human race, shall be no more remembered or renewed. The approaching happy state of the church is described under a variety of images. He shall be thought to die in his youth, and for his sins, who only lives to the age of a hundred years. The event alone can determine what is meant; but it is plain that Christianity, if universal, would so do away violence and evil, as greatly to lengthen life. In those happy days, all God's people shall enjoy the fruit of their labours. Nor will children then be the trouble of their parents, or suffer trouble themselves. The evil dispositions of sinners shall be completely moritified; all shall live in harmony. Thus the church on earth shall be full of happiness, like heaven. This prophecy assures the servants of Christ, that the time approaches, wherein they shall be blessed with the undisturbed enjoyment of all that is needful for their happiness. As workers together with God, let us attend his ordinances, and obey his commands.
