'Forever' in the Bible

“You evict the women (widows) of My people,Each one from her pleasant house;From her [young, fatherless] children you take away My splendor and blessing forever [by putting them among the pagans, away from Me].

For all the peoples [now] walkEach in the name of his god [in a transient relationship],As for us, we shall walk [securely]In the name of the Lord our [true] God forever and ever.

“I shall make the lame a [godly] remnantAnd the outcasts a strong nation;And the Lord shall reign over them in Mount ZionFrom this time on and forever.

Who is a God like You, who forgives wickednessAnd passes over the rebellious acts of the remnant of His possession?He does not retain His anger forever,Because He [constantly] delights in mercy and lovingkindness.
