Charles Ellicott Commentary Isaiah 65:17

"For, behold, I create new heavens and a new earth; and the former things shall not be remembered, nor come into mind." — Isaiah 65:17 (ASV)

Behold, I create new heavens ... —The thought reappears in many forms in the New Testament—verbally in 2 Peter 3:13; Revelation 21:1, substantially in the restitution of all things (Acts 3:21), in the manifestation of the sons of God (Romans 8:19). The “former things,” the sin and sorrow of the past, shall then fade away from the memory of God’s people, absorbed in the abounding and everlasting joy.
