Update

And, “You, Lord, in the beginning, laid the foundation of the earth. The heavens are the works of your hands. They will perish, but you continue. They all will grow old like a garment does. You will roll them up like a mantle, and they will be changed; but you are the same. Your years will not fail.”
Hebrews 1:10-12 (WEB)
