Psalms Chapter 98
Psalm 98 is the result celebrated by Israel on earth. Jehovah has made known His salvation, and remembered His mercy and truth towards Israel. All the land (or earth) is summoned to celebrate Jehovah as king. The heavens are not summoned here, as in Psalm 96. They are already filled with His glory, and the angels have been called to worship; but the sea and its fullness, and the world and its inhabitants are to rejoice before Jehovah, who comes to judge the earth and the whole world.
