'Forever' in the Bible

Now unto the King eternal, immortal, invisible, the only God, be honor and glory forever and ever. Amen.

The Lord will deliver me from every evil work, and will save me unto his heavenly kingdom: to whom be the glory forever and ever. Amen.

Wild waves of the sea, foaming out their own shame; wandering stars, for whom the blackness of darkness hath been reserved forever.
