'Forever' in the Bible

He will build a Temple dedicated to my Name, and I will make the throne of his kingdom last forever.

Your dynasty and your kingdom will remain forever in my presence your throne will be secure forever."'"

May your name be made great forever with the result that it is said that the LORD of the Heavenly Armies is God over Israel, and that the household of your servant David may be established before you.

So may it please you to bless the household of your servant, so that it might remain forever in your presence, because you, Lord GOD, have spoken, and from your blessing may the household of your servant be blessed forever."

Great is the salvation he brings to his king, showing gracious love to his anointed, to David and to his offspring forever.
