You mean same words?
Revelation 21 does not state "birth" and "death" and "sinners".
Why do you reject there is birth and death in Isaiah 65?
And the 1,000 years is at the end of the world as well.
Isa 65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Isa 65:18 But be ye glad and rejoice for ever in that which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy.
Isa 65:19 And I will rejoice in Jerusalem, and joy in my people: and the voice of weeping shall be no more heard in her, nor the voice of crying.
Isa 65:20 There shall be no more thence an infant of days, nor an old man that hath not filled his days:
for the child shall die an hundred years old; but the sinner being an hundred years old shall be accursed.
Death still exists here.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Rev 21:3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.
Rev 21:4 And God shall wipe away all tears from their eyes;
and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
The two passages do not match and are NOT the same.
