'Forevermore' in the Bible

There shall be no end to the increase of His government and of peace,[He shall rule] on the throne of David and over his kingdom,To establish it and to uphold it with justice and righteousnessFrom that time forward and forevermore.The zeal of the Lord of hosts will accomplish this.

Now, go, write it on a tablet before themAnd inscribe it on a scroll,So that it may serve in the time to comeAs a witness [against them] forevermore.
