Vidqun,
Thank you for that source, which I managed to locate. The context of your first citation continues with the following, to which your final sentence refers.

=================================
The first expression of this group, or the fourth in the whole number, is “to bring in everlasting righteousness.” After the entire setting aside of sin must come a righteousness which shall never cease. That [Hebrew text] does not mean “happiness of the olden time” (Bertholdt, Rösch), nor “innocence of the former better times” (J. D. Michaelis), but “righteousness,” requires at present no further proof. Righteousness comes from heaven as the gift of God (Ps. lxxxv. 11-14; Isa. li. 5-8), rises as a sun upon them that fear God (Mal. iii. 20), and is here called everlasting, corresponding to the eternity of the Messianic kingdom (cf. ii. 44, vii. 18, 27). [Same Hebrew text] comprehends the internal and the external righteousness of the new heavens and the new earth, 2 Pet. iii. 13. This fourth expression forms the positive supplement of the first: in the place of the absolutely removed transgression is the perfected righteousness. (Biblical Commentary on The Old Testament, Keil And Delitzsch (1884), on Chap. IX. 24-27, page 343)
