'Forever' in the Bible

"Because all of the people will walk, each person in the name of his God, and we will walk in the name of the LORD our God forever and ever.

I will transform the lame into survivors, and those who were scattered into a strong nation; and the LORD will reign over them in Mount Zion, now and forever."

Is there any God like you, forgiving iniquity, passing over transgressions by the survivors who are your heritage? He is not angry forever, because he delights in gracious love.
