Arise, O God,.... These are the words of the prophet, or of the church, whom he represents, addressing Christ, who is God over all; that seeing there was such a corruption and degeneracy in the world, and such wretched perversion of justice, that he would arise and exert himself, and show himself strong on the behalf of his people: judge the earth: who is the Judge of the whole earth, to whom all judgment is committed, and who will judge the world in righteousness: for thou shalt inherit all nations; which he will do in the latter day, when he shall be King over all the earth, and the Heathen shall be given him for his inheritance, he being heir of all things; and universal justice will not take place in the world till that time comes; and therefore it is to be wished and prayed for, as by the prophet and church here.
