Psalm 98: "1 Oh sing to the LORD a new song, for he has done marvelous things! His right hand and his holy arm have worked salvation for him. 2 The LORD has made known his salvation; he has revealed his righteousness in the sight of the nations. 3 He has remembered his steadfast love and faithfulness to the house of Israel. All the ends of the earth have seen the salvation of our God.
"4 Make a joyful noise to the LORD, all the earth; break forth into joyous song and sing praises! 5 Sing praises to the LORD with the lyre, with the lyre and the sound of melody! 6 With trumpets and the sound of the horn make a joyful noise before the King, the LORD!
"7 Let the sea roar, and all that fills it; the world and those who dwell in it! 8 Let the rivers clap their hands; let the hills sing for joy together 9 before the LORD, for he comes to judge the earth. He will judge the world with righteousness, and the peoples with equity."
