'Forever' in the Bible

‘Between morning and evening they are broken in pieces;Unobserved, they perish forever.

“I waste away; I will not live forever.Leave me alone, for my days are but a breath.

“You forever overpower him and he departs;You change his appearance and send him away.

“That with an iron stylus and leadThey were engraved in the rock forever!

He perishes forever like his refuse;Those who have seen him will say, ‘Where is he?’

“There the upright would reason with Him;And I would be delivered forever from my Judge.

“He does not withdraw His eyes from the righteous;But with kings on the throneHe has seated them forever, and they are exalted.

“Will he make a covenant with you?Will you take him for a servant forever?
