Say among the heathen that the Lord reigneth (comp. Psalms 93:1; Psalms 97:1; Psalms 99:1). The world also shall be established that it shall not be moved. When God takes his throne, and manifestly reigns, the earth is at once "established," settled, placed on a firm footing (see the comment on Psalms 93:1, where exactly the same words occur).
He shall judge the people righteously (comp. Psalms 96:13). God, the Deliverer of old time (Psalms 96:3, Psalms 96:4), God, the King of the whole earth (Psalms 96:10), is also God the Judge, who gives sentence on the "peoples" with equity.
