The LORD hath brought forth our righteousness: come, and let us declare in Zion the work of the LORD our God.
The Lord hath ... Next after the speech of the confederates of Babylon comes that of the Jews, celebrating with thanksgivings the promise-keeping faithfulness of their covenant God.
Brought forth - (Psalms 37:6, "He shall bring forth thy righteousness as the light"). Our righteousness - not the Jews' merits, but God's faithfulness to Himself and to His covenant, which constituted the "righteousness" of His people - i:e., their justification in their controversy with Babylon, the cruel enemy of God and His people. (Compare Jeremiah 23:6, "The Lord our righteousness;" Micah 7:9.) Their righteousness is His righteousness.
Come, and let us declare in Zion the work of the Lord our God - (Psalms 102:13-21, "When the Lord shall build up Zion, He shall appear in his glory ... to declare the name of the Lord in Zion, and His praise in Jerusalem").
