Charles H. Spurgeon on Psalms 93:1

The LORD. He describes God by the name Jehovah, partly, to lead us to think of the God of Israel, accustomed by this name to be distinguished from the gods of the nations; partly, to call to mind the virtues of veracity, grace and justice, comprehended by this name, and now clearly made known... When he says, Jehovah reigns, without adding any restriction, or mentioning any people, it would seem that the Kingdom of Jehovah is to be taken absolutely and generally, with equal reference to the government of the world and the church. In the former sense Jehovah may be said to reign, not as if He then at last begun to reign, but because He proved himself to be the King of the world in an extraordinary way, by giving public and manifest signs; by which it was clearly established that Jehovah is the true God, the Creator of heaven and earth, the Lord and Ruler of the whole universe, and a just and equitable judge, in inflicting notable judgements upon sinners, in casting down the idols, and vindicating the cause of true religion and virtue. This meaning I regard as contained in the general proposition: yet directly in its primary signification I understand the Kingdom of God in His Church, partly, because God is here said to vindicate the cause of religion, and of his people; partly, he is said, in Ps 99:1 to show himself exalted in Zion, and there to undertake the Kingdom, Isa 24:23, and often elsewhere in the Prophetic word; and lastly, because Jehovah, the King of his people, he himself who reigns, is set forth as the ruler of the universe. He is the King therefore of his people, He has his Kingdom in their midst, but to Him all things in heaven and earth are subject as well. In this latter sense, therefore, the phrase, Jehovah has reigned, will stand for, He has undertaken the Kingdom, He is become King, as it is often used in the histories of the Kings of Judah and Israel; so also in Isa 28:23, and elsewhere... When He is said to have taken the Kingdom in the midst of his people, it must not be understood absolutely, but in a restricted sense, in reference partly to the manner and form of rule, being more or less theocratic;partly, to the displays of the Divine Majesty, being more or less conspicuous; and partly, to the servile or afflicted state of his people, as extending from the Babylonish exile to the time of the Maccabees. In which times God is said to have taken the Kingdom, in many other prophecies beside this, Isa 24:21-23, Obad., ult. Mic 4:6-8. Venema.
