The psalm opens with three calls to sing to the Lord: a new song, all the earth; bless his name; tell of his salvation from day to day. It then asks us to declare his glory among the nations and his marvelous works among all peoples. The reason is that the Lord is great and greatly to be praised, to be feared above all gods, for the gods of the peoples are worthless idols, but the Lord made the heavens. Splendor and majesty are before him, strength and beauty in his sanctuary.
In verses 7-9 the families of the peoples are invited to ascribe to the Lord glory and strength, to bring an offering and come into his courts, and to worship him in the splendor of holiness. All the earth is to tremble before him.
Verse 10 commands us to say among the nations: the Lord reigns, the world is established and he will judge the peoples with equity. Then the heavens rejoice, the earth is glad, the sea roars and all that fills it, the field exults and the trees of the forest sing for joy before the Lord, for he comes to judge the earth in righteousness and the peoples in his faithfulness.
