The psalm begins with a request: give the king your justice, O God, and your righteousness to the royal son. Then he will judge the people with righteousness and the afflicted with justice. The mountains will bring peace to the people and the hills righteousness. He will defend the afflicted, save the children of the needy and crush the oppressor.
Verses 5 to 7 ask that the king live as long as the sun and moon endure. He will be like rain that falls on the mown grass, like showers that water the earth. In his days the righteous will flourish and peace will abound until the moon is no more. Verses 8 to 11 describe a dominion from sea to sea and from the River to the ends of the earth. Desert dwellers will bow before him and his enemies will lick the dust. The kings of Tarshish and of the coastlands will render tribute, and the kings of Sheba and Seba will bring gifts. All kings will bow down to him and all nations will serve him.
The reason appears in verses 12 to 14: he delivers the needy who cry out, the poor and those who have no helper. He has pity on the weak and saves the lives of the needy. He redeems their life from oppression and violence, and their blood is precious in his sight.
In verses 15 to 17, they pray that he live, receive gold of Sheba and be blessed always. There will be abundance of grain on the tops of the mountains, and its fruit will rustle like Lebanon. May his name endure forever, and may all nations be blessed in him. Verses 18 to 19 bless the Lord God, the God of Israel, who alone does wondrous things, and ask that the whole earth be filled with his glory. Verse 20 is a note closing the book.
