'Forevermore' in the Bible

Of the growth of his government and peace there will be no end. He will rule over his kingdom, sitting on the throne of David, to establish it and to uphold it with justice and righteousness from this time onward and forevermore. The zeal of the LORD of the Heavenly Armies 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.

But be happy and rejoice forevermore over what I am about to create! For look, I am ready to create Jerusalem to be a source of joy, and her people to be a source of happiness.
