'Forever' in the Bible

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

“I waste away and loathe my life; I will not live forever.Let me alone, for my days are but a breath [futile and without substance].

“You prevail forever against him and overpower him, and he passes on;You change his appearance and send him away [from the presence of the living].

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

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

“There the righteous and upright could reason with Him;So I would be acquitted forever by my Judge.

“He does not withdraw His eyes from the righteous [those in right standing with Him];But with kings upon the throneHe has seated them forever, and they are exalted.

“Will he make a covenant or an arrangement with you?Will you take him for your servant forever?
