'Forever' in the Bible

They are destroyed between morning and evening; they perish forever without anyone regarding it.

I loathe it; I do not want to live forever; leave me alone, for my days are a vapor!

that with an iron chisel and with lead they were engraved in a rock forever!

he will perish forever, like his own excrement; those who used to see him will say, 'Where is he?'

There an upright person could present his case before him, and I would be delivered forever from my judge.

He does not take his eyes off the righteous; but with kings on the throne he seats the righteous and exalts them forever.
