'Ever living' in the Bible

When I saw Him, I fell at His feet as if I were dead. But He laid His right hand upon me and said, "Do not be afraid: I am the First and the Last, and the ever-living One.

And I saw another angel coming from the east and carrying a seal belonging to the ever-living God. He called in a loud voice to the four angels whose work it was to injure the earth and the sea.
