Psalm 102:26
“They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed:”
KJV
Read in Psalm 102Meaning
The created order is portrayed as temporary compared with God. The image is theological poetry, not a timetable for cosmic destruction.
Read carefully
It contrasts creation's transience with God's permanence without supplying a chronology.
Reflection
Remember that the psalm locates permanence in God rather than in created things.
