Psa 98:1 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.
Psa 98:2 The LORD has made his salvation known
and revealed his righteousness to the nations.

Psa 98:3 He has remembered his love
and his faithfulness to the house of Israel;
all the ends of the earth have seen
the salvation of our God.

Psa 98:4 Shout for joy to the LORD, all the earth,
burst into jubilant song with music;

Psa 98:5 make music to the LORD with the harp,
with the harp and the sound of singing,

Psa 98:6 with trumpets and the blast of the ram’s horn—
shout for joy before the LORD, the King.

Psa 98:7 Let the sea resound, and everything in it,
the world, and all who live in it.

Psa 98:8 Let the rivers clap their hands,
let the mountains sing together for joy;

Psa 98:9 let them sing before the LORD,
for he comes to judge the earth.
He will judge the world in righteousness
and the peoples with equity.

N.T. Wright (Paul and the faithfulness of God) notes that the pagan neighbours of the Jews had very little by way of future hope, compared with what is expressed here (see also Isa 11:1-4, 6-9):-

‘A world set free both from human injustice and from ‘natural’ violence; a world in which oceans and mountains themselves will rejoice at a new fulfilment; a world in which all peoples will celebrate the fact that everything has been set right at last. That is the ancient Israelite vision, variously re-expressed in Jewish texts across the second-temple period. This is not simply a hope beyond the world. It is a hope for the world. The difference is all-important, and is rooted, as those two extracts and many others indicate, in the ancient Israelite and Jewish belief that the true God, Israel’s God, was the creator of earth as well as heaven. Sooner or later he would put all things right, and there would be—you can feel it in those texts—a cosmic sigh of relief.’
